Method setDefault()

Specify default values for some function arguments.

Usage
PivotTable$setDefault(...)
Arguments
...

Default values to specify. See details.

Details

Defaults can be set for the following arguments of 'pt$addRowDataGroups()' and 'pt$addColumnDataGroups()': 'logical' values: 'addTotal', 'expandExistingTotals', 'visualTotals'. 'character' values: 'totalPosition', 'totalCaption'. 'list' or 'logical' values: 'outlineBefore', 'outlineAfter', 'outlineTotal'.
Errors are generated for default values that could not be set.
Warnings are generated for attempts to set defaults that aren't supported.
See the "A1. Appendix" vignette for more details.

Returns

No return value.

Method getDefault1()

Get the default value of an argument.

Usage
PivotTable$getDefault1(argValue = NULL, useDefault = NULL)
Arguments
argValue

The name and value of the argument.

useDefault

Specify 'TRUE' to use the default.

Details

Both the argument name and argument value are taken from the 'argValue' argument. The name is obtained from 'as.character(substitute(argValue))'. This function is designed to easily slot into existing code, e.g. 'getDefault1(addTotal, missing(addTotal))'.

Returns

The current value of the argument or the default value.

Method getDefault2()

Get the default value of an argument.

Usage
PivotTable$getDefault2(argName = NULL, argValue = NULL, useDefault = NULL)
Arguments
argName

The name of the argument.

argValue

The current value of the argument.

useDefault

Specify 'TRUE' to use the default.

Returns

The current value of the argument or the default value.

Method getDefault3()

Get the default value of an argument.

Usage
PivotTable$getDefault3(argName)
Arguments
argName

The name of the argument.

Returns

The default value.

Method getNextInstanceId()

Get the next unique object instance identifier.

Usage
PivotTable$getNextInstanceId()
Details

R6 classes cannot be easily compared to check if two variables are both referring to the same object instance. Instance ids are a mechanism to work around this problem. Each data group and cell is assigned an instance id during object creation, which enables reliable reference comparisons.

Returns

An integer instance id.

Method addData()

Add a data frame with the specified name to the pivot table.

Usage
PivotTable$addData(dataFrame = NULL, dataName = NULL)
Arguments
dataFrame

The data frame to add.

dataName

The name to be used to refer to the data frame. If no name is specified, the data frame variable name from the calling code is used, retrieved via 'deparse(substitute(dataFrame))'.

Details

The name is used to refer to the data frame when generating data groups or defining calculations. The pivot table tracks the first data frame added as the default data frame, so if only a single data frame is used, it is typically not necessary to ever explicitly refer to the name. Pivot tables are typically based on a single data frame, however it is possible to build a pivot table that uses data from multiple data frames.

Returns

The 'PivotData' object managing the data frames for the pivot table.

Method addTotalData()

Add a data frame containing totals data with the specified name and variables to the pivot table.

Usage
PivotTable$addTotalData(
  dataFrame = NULL,
  dataName = NULL,
  variableNames = NULL
)
Arguments
dataFrame

The data frame to add.

dataName

The name of the data frame to associate these totals with.

variableNames

A vector specifying how the aggregate data/totals in the data frame are grouped.

Details

When generating pivot tables, the package typically calculates cell values. However, the package can also use provided values (i.e. carry out no calculations). This presents a challenge in that the sub-totals and totals in a pivot table display values at a higher aggregation level than the normal cells in the body of the pivot table. This method allows further data frames to be specified that contain aggregated versions of the data. See the "Calculations" vignette for details and an example.

Returns

No return value.

Method getColumnGroupsByLevel()

Retrieve the data groups at the specified level or levels in the column groups hierarchy.

Usage
PivotTable$getColumnGroupsByLevel(level = NULL, collapse = FALSE)
Arguments
level

An integer value or vector specifying one or more level numbers. Level 1 represents the first visible level of data groups.

collapse

A logical value specifying whether the return value should be simplified. See details.

Details

If 'level' is a vector: If 'collapse' is 'FALSE', then a list of lists is returned, if 'collapse' is 'TRUE', then a single combined list is returned.

Returns

A list containing 'PivotDataGroup' objects.

Method getTopColumnGroups()

[Deprecated: Use topColumnGroups instead] Retrieve the first level of column data groups.

Usage
PivotTable$getTopColumnGroups()
Returns

A list containing 'PivotDataGroup' objects.

Method getLeafColumnGroup()

Retrieve the leaf-level data group associated with a specific column or columns.

Usage
PivotTable$getLeafColumnGroup(c = NULL)
Arguments

calculationGroupName

The calculation group that the new data groups are related to.

expandExistingTotals

Default 'FALSE', which means totals are not broken down in multi-level hierarchies.

addTotal

Default 'TRUE', which means sub-total and total data groups are automatically added.

onlyAddGroupIf

A filter expression that can be used to more finely control whether data groups are created at different locations in the hierarchy. There must be at least one row that matches this filter and the filters from the ancestor groups in order that the child group is created. E.g. 'MaxDisplayLevel>5'.

preGroupData

Default 'TRUE', which means that the pivot table pre-calculates the distinct combinations of variable values to reduce the CPU time and elapsed time required to generate data groups. Cannot be used in conjunction with the

baseStyleName

The name of the style applied to this data group (i.e. this row/column heading). The style must exist in the 'PivotStyles' object associated with the PivotTable.

styleDeclarations

CSS style declarations that can override the base style, expressed as a list, e.g. 'list("font-weight"=bold")'.

Details

There are broadly three different ways to call 'addColumnDataGroups()':
(1) dataName=name, fromData=TRUE, onlyCombinationsThatExist=TRUE - which considers the ancestors of each existing data group to generate only those combinations of values that exist in the data frame.
(2) dataName=name, fromData=TRUE, onlyCombinationsThatExist=FALSE - which ignores the ancestors of each existing data group and simply adds every distinct value of the specified variable under every existing data group, which can result in combinations of values in the pivot table that don't exist in the data frame (i.e. blank rows/columns in the pivot table).
(3) fromData=FALSE, explicitListOfValues=list(...) - simply adds every value from the specified list under every existing data group.

Returns

A list of new 'PivotDataGroup' objects that have been added.

"value" sorts by the raw (i.e. unformatted) group value.
"caption" sorts by the formatted character group caption.
"calculation" sorts using one of the calculations defined in the pivot table.
"customValue" sorts by the raw (i.e. unformatted) group value according to the specified custom sort order.

A character value used as the row-group column caption when row group headers are rendered.

outlineBefore

Default 'FALSE' to disable the creation of outline header groups. Specify either 'TRUE' or a list of outline group settings to create outline header groups. See the "Regular Layout" vignette for details.

outlineAfter

Default 'FALSE' to disable the creation of outline footer groups. Specify either 'TRUE' or a list of outline group settings to create outline footer groups. See the "Regular Layout" vignette for details.

outlineTotal

Default 'FALSE' to disable the creation of outline totals. Specify either 'TRUE' or a list of outline group settings to create outline totals. See the "Regular Layout" vignette for details.

onlyAddOutlineChildGroupIf

A filter expression that can be used to more finely control whether outline child groups are created at different locations in the hierarchy. There must be at least one row that matches this filter and the filters from the ancestor groups in order that the outline child group is created. E.g. 'MaxDisplayLevel>5'. See the "Regular Layout" vignette for an example.

Details

There are broadly three different ways to call 'addRowDataGroups()':
(1) dataName=name, fromData=TRUE, onlyCombinationsThatExist=TRUE - which considers the ancestors of each existing data group to generate only those combinations of values that exist in the data frame.
(2) dataName=name, fromData=TRUE, onlyCombinationsThatExist=FALSE - which ignores the ancestors of each existing data group and simply adds every distinct value of the specified variable under every existing data group, which can result in combinations of values in the pivot table that don't exist in the data frame (i.e. blank rows/columns in the pivot table).
(3) fromData=FALSE, explicitListOfValues=list(...) - simply adds every value from the specified list under every existing data group.

Returns

A list of new 'PivotDataGroup' objects that have been added.

Method normaliseRowGroups()

Details

There are five ways to specify the part(s) of a pivot table to apply styling to:
(1) By specifying a list of data groups using the 'groups' argument.
(2) By specifying a list of cells using the 'cells' argument.
(3) By specifying a single cell using the 'rFrom' and 'cFrom' arguments.
(4) By specifying a rectangular cell range using the 'rFrom', 'cFrom', 'rTo' and 'cTo' arguments.
(5) By specifying a vector of rowNumbers and/or columnNumbers. If both rowNumbers and columnNumbers are specified, then the cells at the intersection of the specified row numbers and column numbers are styled.
If both rFrom/rTo and rowNumbers are specified, then rFrom/rTo constrain the row numbers specified in rowNumbers.
If both cFrom/cTo and columnNumbers are specified, then cFrom/cTo constrain the column numbers specified in columnNumbers.
See the "Styling" and "Finding and Formatting" vignettes for more information and many examples.

)
Arguments
styleProperty

The name of the style property to set on the specified cells, e.g. background-color.

cells

A list containing 'PivotCell' objects.

valueType

The type of style value to be set. Must be one of: "text", "character", "number", "numeric", "color" or "colour".
"text" and "character" are equivalent. "number" and "numeric" are equivalent. "color" and "colour" are equivalent.

mapType

The type of mapping to be performed. The following mapping types are supported:
(1) "value" = a 1:1 mapping which maps each specified "from" value to the corresponding "to" value, e.g. 100 -> "green".
(2) "logic" = each from value is logical criteria. See details.
(3) "range" = values between each pair of "from" values are mapped to the corresponding "to" value, e.g. values in the range 80-100 -> "green" (more specifically values greater than or equal to 80 and less than 100).
(4) "continuous" = rescales values between each pair of "from" values into the range of the corresponding pair of "to" values, e.g. if the "from" range is 80-100 and the corresponding "to" range is 0.8-1, then 90 -> 0.9.
"continuous" cannot be used with valueType="text"/"character".

mappings

The mappings to be applied, specified in one of the following three forms:
(1) a list containing pairs of values, e.g. 'list(0, "red", 0.4, "yellow", 0.8, "green")'.
(2) a list containing "from" and "to" vectors/lists, e.g. 'list(from=c(0, 0.4, 0.8), to=c("red", "yellow", "green"))'.
(3) a custom mapping function that will be invoked once per cell, e.g. 'function(v, cell) if(isTRUE(v>0.8)) return("green") '.
Mappings must be specified in ascending order when valueType="range" or valueType="continuous".
If a custom mapping function is specified, then the valueType and mapType parameters are ignored.

styleLowerValues

A logical value, default 'FALSE', that specifies whether values less than the lowest specified "from" value should be styled using the style specified for the lowest "from" value. Only applies when valueType="range" or valueType="continuous".

styleHigherValues

A logical value, default 'TRUE', that specifies whether values greater than the highest specified "from" value should be styled using the style specified for the highest "from" value. Only applies when valueType="range" or valueType="continuous".

Details

'mapStyling()' is typically used to conditionally apply styling to cells based on the value of each individual cell, e.g. cells with values less than a specified number could be coloured red.
mapType="logic" maps values matching specified logical criteria to specific "to" values. The logical criteria can be any of the following forms (the first matching mapping is used):
(1) a specific value, e.g. 12.
(2) a specific value equality condition, e.g. "v==12", where v represents the cell value.
(3) a value range expression using the following abbreviated form: "value1<=v<value2", e.g. "10<=v<15". Only "<" or "<=" can be used in these value range expressions.
(4) a standard R logical expression, e.g. "10<=v && v<15".
Basic R functions that test the value can also be used, e.g. is.na(v).
See the "Styling" and Finding and Formatting" vignettes for more information and many examples.

Returns

No return value.

Method evaluateCells()

Calculate the cell values in the body of the pivot table.

Usage
PivotTable$evaluateCells()
Details

This method rarely needs to be called explicitly, since other methods will invoke it if needed.

Returns

No return value.

Method evaluatePivot()

variableValues

A list specifying the variable names and values to find, e.g. 'variableValues=list("PowerType"=c("DMU", "HST"))'.
Specify "**" as the variable value to match totals for the specified variable.
Specify "!*" as the variable value to match non-totals for the specified variable.
NB: The totals/non-totals criteria above won’t work when visual totals are used.

totals

A word that specifies how totals are matched (overrides the finer settings above) - must be one of "include" (default), "exclude" or "only".

calculationNames

A character vector specifying the name/names of the calculations to find.

minValue

A numerical value specifying a minimum value threshold.

maxValue

A numerical value specifying a maximum value threshold.

exactValues

A vector or list specifying a set of allowed values.

valueRanges

A vector specifying one or more value range expressions which the cell values must match. If multiple value range expressions are specified, then the cell value must match any of one the specified expressions. See details.

includeNull

specify TRUE to include 'NULL' in the matched cells, FALSE to exclude 'NULL' values.

includeNA

specify TRUE to include 'NA' in the matched cells, FALSE to exclude 'NA' values.

emptyCells

A word that specifies how empty cells are matched - must be one of "include" (default), "exclude" or "only".

outlineCells

A word that specifies how outline cells are matched - must be one of "include", "exclude" (default) or "only".

A vector of column numbers that specify the columns or cells to constrain the search.

cellCoordinates

A list of two-element vectors that specify the coordinates of cells to constrain the search.

groups

rowGroups

A 'PivotDataGroup' object or a list of 'PivotDataGroup' objects on the rows axis. The cells to be searched must be related to at least one of these row groups. If both 'rowGroups' and 'columnGroups' are specified, then the cells to be searched must be related to at least one of the specified row groups and one of the specified column groups.

columnGroups

A 'PivotDataGroup' object or a list of 'PivotDataGroup' objects on the columns axis. The cells to be searched must be related to at least one of these column groups. If both 'rowGroups' and 'columnGroups' are specified, then the cells to be searched must be related to at least one of the specified row groups and one of the specified column groups.

rowColumnMatchMode

Either "simple" (default) or "combinations":
"simple" specifies that row and column arguments are considered separately (logical OR), e.g. rowNumbers=1 and columnNumbers=2 will match all cells in row 1 and all cells in column 2.
"combinations" specifies that row and column arguments are considered together (logical AND), e.g. rowNumbers=1 and columnNumbers=2 will match only the cell single at location (1, 2).
Arguments 'rowNumbers', 'columnNumbers', 'rowGroups' and 'columnGroups' are affected by the match mode. All other arguments are not.

cells

A 'PivotCell' object or a list of 'PivotCell' objects to constrain the scope of the search.

lowN

Find the first N cells (ascending order, lowest values first).

highN

Find the last N cells (descending order, highest values first).

Details

The valueRanges parameter can be any of the following forms:
(1) a specific value, e.g. 12.
(2) a specific value equality condition, e.g. "v==12", where v represents the cell value.
(3) a value range expression using the following abbreviated form: "value1<=v<value2", e.g. "10<=v<15". Only "<" or "<=" can be used in these value range expressions.
(4) a standard R logical expression, e.g. "10<=v && v<15".
