Re: [R] building a data.frame from a matrix: preventing conversion to factors

Thanks for your reply. I have tried the reproducible example you have provided (thanks!) in 3 different versions of R, and get what you get in R version 2.5.1, but in 2.3.1 (which I normally use) and 2.1.0 (which I still have installed) I get factors. I guess this means I should switch to the ne

I can prevent conversion of the vectors by using I(), as explained in help(data.frame). However, this doesn't help with the matrices: if I
