How to assigen column of matrix

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.

Dear Minghua Yao,

Commands of the form AA[, i] <- A do indeed work, although the number of 
elements in the i-th row of AA has to be a multiple of the number of 
elements in A. Perhaps you can specify in more detail what it is that you 
want to do and the nature of the error that you encountered.

I hope that this helps,
  John
