[R] changing the value of a variable from inside a function

[tom wright]

Michael,
I feel sure people are going to come up with other better suggestions
here but does <- work for you?
test <- matrix(NA,nrow=4,ncol=3)
test[1,] <- c(1,2,3)
blah <- function(i){
   test[i,] <<- c(0,1,2) + i
   return(test)
}
