In InferenceTechnologies/tableMatrix: Combines 'data.table' and 'matrix' Classes

Description

tableMatrix method to get or set a row from the matrix attribute.

Usage

## S3 method for class 'tableMatrix'
getRow(obj, i = NULL, repo = NULL, ...)

## S3 method for class 'tableMatrix'
setRow(obj, value, i = NULL, repo = NULL, ...)

Arguments

obj	tableMatrix object.
i	Integer. Row index in tab.
repo	Numeric vector. Vector with 2 elements - matN and matRow.
...	Passed arguments.
value	Vector for setting value.

Value

Row from the matrix part.

Examples

data(images8By8)
data(images10By10)

# Create tableMatrix from images8By8 and images10By10
TM <- tableMatrix(list(images8By8, images10By10), list(1:3, 1:3),
list(4:ncol(images8By8),4:ncol(images10By10)))

# Row 91 in tab(TM) corresponds to second matrix, first row 
row <- getRow(TM, 91)

# Row 91 in tab(TM) corresponds to second matrix, first row 
getRow(TM, repo=c(2,1))

# Change matrix row corresponding to row 91 in tab(TM) 
TM <- setRow(TM, rep(2,length(row)), 91)
getRow(TM, 91)
