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
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) - nams
newdata -
# 2. create one new row for each case in level.1 and level.2
# the new reshaped data.frame would should look like this:
# indiv factorcovar case.id
# A level.1 4.6141051
# A level.1 4.6141052
# A level.2 31.0644051
# A level.2 31.0644052

Dear all,
I'm having a few problems trying to reshape a data frame. I tried with
reshape{stats} and melt{reshape} but I was missing something. Any help is
very welcome. Please find details below:
#
# data in its original shape:
indiv - rep(c(A,B),c(10,10))
