Hi all, I need to create a data.frame from a variable number of vectors. The number of these vectors could change so I need a dinamic way to group all in a data.frame. The number is length(abc). e.g. vectors in my workspace N1 <-c(1,2,3,4) N2 <-c(1,2,3,4) N3 <-c(1,2,3,4) abc <-c(1,2,3) the data.frame I want to create: tcm <-data.frame(OneVector, TwoVector, paste("N",1:length(abc))) Obviously :) if I am here this approach doesn't work, so any kind of tip is welcome. Cheers -- Daniele Medri
