Dear R People:
I have a data frame with the following column names:
> names(funky)
[1] "UHD.1" "UHD.2" "UHD.3" "UHD.4" "L..W..1" "L..W..2" "L..W..3"
[8] "L..W..4" "B..W..1" "B..W..2" "B..W..3" "B..W..4" "W..B..1" "W..B..2"
[15] "W..B..3" "W..B..4" "B..G..1" "B..G..2" "B..G..3" "B..G..4"
I would like to extract the letters from them; no periods, no numbers.
I tried the following:
> grep("[A:Z]",names(funky))
integer(0)
But this doesn't do it.
I've also been experimenting with strsplit, but no luck yet.
Any help would be much appreciated.
Thanks,
Sincerely,
Erin
