Hello again,
I have one question on subscripting matrix. Let say I have following matrix:
> Mat <- matrix(1:9, 3)
> colnames(Mat) <- c("a", "b", "a")
> Mat
a b a
[1,] 1 4 7
[2,] 2 5 8
[3,] 3 6 9
Now I want to fetch data for colnames 'a'.I did following:
> Mat[, "a"]
[1] 1 2 3
However it is not taking second 'a' colume. Basically I expected to
get 1st and 3rd columns
Can somebody tell me how to achieve that?
Thanks and regards,
