[R] there was a function...

[Peter Malewski]

I'm currently making xyplots from repeated-measurements data. With s+
there was a function make.groups. 

I have rewrote this:

make.groups <-function (x) {
  if (is.data.frame(x)) 
    x <- as.matrix(x)
  d <- dim(x)
  data.frame(which = rep(1:dim(x)[2], rep(dim(x)[1], dim(x)[2])), 
             id = rep(1:dim(x)[1], dim(x)[2]), data = c(x))
}


so far so good. But I'm sure there were builtin-functions that do nearly the
same, but I cannot remember the names ????

Thanks
Peter
