Dear Chuck, John, Vikas, and useRs,
thank you very much for your great suggestions.
I received three replies providing different ways to reshape my original
data.frame (original question at the bottom). There are however some
discrepancies in their results (most likely because I didn't explain my

Here is a very clumsy way to do it but I think it
works
fact1 <- rep("level.1", length(mydat[,1]))
fact2 <- rep("level.2", length(mydat[,1]))
lels <- c(fact1,fact2)
nams <- c("indiv", "case.id", "covar")
set1 <- mydat[, c(1,2,3)] ; names(set1) <- nams
set2 <- mydat[,c(1, 4,5)] ; names(set2) <-

Dear all,
I'm having a few problems trying to reshape a data frame. I tried with

very welcome. Please find details below:

indiv <- rep(c("A","B"),c(10,10))
