[R] Problem with cat() == A related question

[Peng, C]

Code:

> fn1 <- function(n = 5){ 
+  mat <- matrix(rnorm(5*5), 5, 5) 
+  cat(print(mat))  
+ } 
> fn1()
           [,1]        [,2]       [,3]        [,4]       [,5]

Question: Is there any control arguments can be used such that fn1() ONLY
prints out the matrix part?
