  fCorr = FactorLevCorr(x)
)

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

# NOT RUN {
 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)
