Hi,
Here are two options. Depending whether the data is already read in
or being created, one or the other may be more useful to you
###########
x1 <- matrix(1:4, ncol = 2)
colnames(x1) <- c("First", "Second")
#OR
x2 <- matrix(1:4, ncol = 2, dimnames = list(NULL, c("First", "Second")))
x1
x2
#########
Cheers,
Josh
