Dear all, I have a vector like this:

z = rep(c("M","F"),c(50,60))

How can I get the following frequency table:

Sex             counts     %
F                60           54.5
M               50           45.5

I try:

DD<- function(data,...)
{

    n       <-  nobs(data)
    out     <-  c(Frequency  = n,
                  k = n/length(data))

    return(out)
}

mApply(z,z,DD) but ....

Best regards
