Hi, A simple question. I want to assign values to columns (or rows) of a matrix. It seems that AA[,i]<-A; # A is a vector or array; doesn't work.
It seems that it does work for me:
AA<-matrix(1:4,2) AA
[,1] [,2] [1,] 1 3 [2,] 2 4
A<-c(10,11) AA[,2]<-A AA
[,1] [,2] [1,] 1 10 [2,] 2 11 if that's what you were trying to do. Note that command lines in R don't end with a ;, but in this case it doesn't matter. -thomas
