Finding hierarchical variable groups

Description

According to the (factor) levels of the variables

Usage

HierarchicalGroups(
  x = NULL,
  mainName = TRUE,
  eachName = FALSE,
  fCorr = FactorLevCorr(x)
)

Arguments

x	Matrix or data frame containing the variables
mainName	When TRUE output list is named according to first variable in group.
eachName	When TRUE variable names in output instead of indices.
fCorr	When non-null, x is not needed as input.

Examples

dataset <- SSBtoolsData("example1")
HierarchicalGroups(dataset[1:2], eachName = TRUE)
HierarchicalGroups(dataset[2:3])
HierarchicalGroups(dataset[1:4], eachName = TRUE)

HierarchicalGroups(SSBtoolsData("magnitude1")[1:4])

 x <- rep(c("A","B","C"),3)
 y <- rep(c(11,22,11),3)
 z <- c(1,1,1,2,2,2,3,3,3)
 zy <- paste(z,y,sep="")
 m <- cbind(x,y,z,zy)
 HierarchicalGroups(m)
