Usage

skew1d(x)

A numeric vector, a numeric matrix or a data frame.

Value

A single value or a vector including the results of skew1d for each variable (in case of numeric matrices or data frames). If variables from data frames are categorical, 'NA' is returned.

data(Election2005)
# }
# NOT RUN {
skew <- skew1d(Election2005)
maxv <- order(skew,decreasing=TRUE)[1:4]
par(mfrow=c(2,2))
for(i in 1:4){
  hist(Election2005[,maxv[i]], xlab="",breaks=30,
  main=paste(names(Election2005[maxv[i]])))
