Hello,
I'd like to pass a column name as the argument for a function, but I'm
getting "NULL" as a return value. Any suggestions? Thanks.
> d <- data.frame(cbind(x=1, y=1:10))
> d
x y
1 1 1
2 1 2
3 1 3
4 1 4
5 1 5
6 1 6
7 1 7
8 1 8
9 1 9
10 1 10
> testing <- function(var) {
+ tst <- d$var[3]
+ tst
+ }
>
> dummy <- testing(y)
> dummy
NULL
