One doesn't generally use cbind.data.frame() directly, but rather through the generic function cbind(). I believe that the following will give you what you want:
fac <- factor(c(rep(1,7), rep(2,3))) cbind(fac, as.data.frame(mat))
where mat is the matrix.
I hope that this helps, John

Hi list, I'd like to make a factor with seven 1s and three 2s using the factor() function. That is,
1 1 1 1 1 1 1 2 2 2
I will then bind this factor to the matrix below using cbind.data.frame().
0.56 0.48 0.22 0.59 0.32 0.64 0.26 0.60 0.25 0.38 0.24 0.45 0.56 0.67 0.78 0.97 0.87 0.79 0.82 0.85
I am new to R and have been using various manuals and have made many attempts without success
any help appreciated.
thanks,
Simon
