In addition to what the others have told you, it looks like you might
be confusing
matrices with data.frames. Please see
?data.frame
I think what you are looking for is
> b <- c('a','b','c')
> c <- c("ee","tt","rr")
> k <- cbind(a,b,c)
> K <- data.frame(a, b, c)
> K
a b c
1 1 a ee
2 2 b tt

Hard to say, not sure what you want to do. But the columns are not denoted by
[a], [b] or [c]. You should learn to use the str function to understand what
various expressions really are, and return to the "Introduction to R" document
that comes with the software. There is a distinct difference b
Hi,
Try:
k[,"a"]
#[1] "1" "2" "3"
k[,"b"]
#[1] "a" "b" "c"
k[,"c"]
#[1] "ee" "tt" "rr"

Problem: when we print the matrix k,
> k
a b c
[1,] "1" "a" "ee"
[2,] "2" "b" "tt"
[3,] "3" "c" "rr"
we can see that rows are represented
