Description

An organizational chart that supports selection.

Usage

1
2
gvisOrgChart(data, idvar = "", parentvar = "", tipvar = "",
  options = list(), chartid)

Arguments

data

a data.frame. The data has to have at least three columns. Each row in the data table describes one node (a rectangle in the graph). Each node (except the root node) has one or more parent nodes. Each node is sized and colored according to its values relative to the other nodes currently shown.

idvar

column name of data describing the ID for each node. It should be unique among all nodes, and can include any characters, including spaces. This is shown on the node. You can specify a formatted value to show on the chart instead, but the unformatted value is still used as the ID.

parentvar

column name of data that match to entries in idvar. If this is a root node, leave this NA. Only one root is allowed.

tipvar

column name of data for the tip variable. Tool-tip text to show, when a user hovers over this node.

options

list of configuration options, see:

\Sexpr[results=rd]{gsub("CHARTNAME", googleChartName, readLines(file.path(".", "inst", "mansections", "GoogleChartToolsURLConfigOptions.txt")))} \Sexpr[results=rd]{paste(readLines(file.path(".", "inst", "mansections", "gvisOptions.txt")))}
chartid

character. If missing (default) a random chart id will be generated based on chart type and tempfile

Details

The gvisOrgChart function reads a data.frame and creates text output referring to the Google Visualisation API, which can be included into a web page, or as a stand-alone page. The actual chart is rendered by the web browser.

Value

\Sexpr[results=rd]{paste(gvisChartName)}

returns list of class \Sexpr[results=rd]{paste(readLines(file.path(".", "inst", "mansections", "gvisOutputStructure.txt")))}
