combine variables to matrix
You can always make a loop (V1 corresponds to column 1, etc.) but as.matrix() is simpler, i.e. in your case data.matrix <- as.matrix(data)

I just got stuck with a quite simple question. I've
just read in an
ASCII table from a plain text file with
read.table(). It's a 1200x1200
table. R has assigned variables for each column:
V1,V2,V3,V4,...
For small data sets
data <- read.table("data.txt");
data.matrix <- cbind(V1,V2,V3);
works. But how could I put together 1200 columns?
I've searched the R mailing help and stumbled upon
this entry:

which doesn't help me. thanks for your help. andre
