Hi, Thank you very much for your help! Here is the coding I used to make it work:
x <- textConnection("A 2.5 3.4 2.7 5.6 5.7 5.4 10.1 9.4 B 5.3 5.4 6.5 7.5 1.3 4.5 10.5 4.1 C 2.1 2.3 2.1 5.4 9.0 4.5 20.1 3.7") dat <- read.table(x) nv <- 2 # Number of variables that are repeated in sequence mkvarying <- function(n)list(paste("V",seq(nv,n,by=nv),sep=""),paste("V",seq(nv+1,n,by=nv),sep="")) reshape(dat,idvar="V1",varying=mkvarying(I(length(dat))),direction="long",timevar=NULL) It is a good idea to first read the data then rearrange them in a second step.
