Dear R People:
Suppose I have the following two character vectors:
xf
[1] "W" NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA NA
> xg
[1] NA "k" "h" NA "g" "r" "j" NA "v" "d" NA "v" NA "z" "r" "r" "i"
>
I want to end up with
"W" "k" "h" ...
What is the best way to achieve this, please? I was thinking that if
there is an exclusive "or" that it might work. I've tried all kinds
of ifs, and ifelse, to no avail.
Thanks,
Erin
