the appropriate wildcard character/symbol to use, please
Did you really use split()?
yes, i did. the output looked like this:
> split(rtt,RTT)
$`1E-.`
[1] CW-W739 CW-W729 CW-W719 CW-W709 CW-W699 CW-W689B CW-W679
CW-W669
...
$`1W-.`
[1] CW-W738 CW-W728 CW-W718 CW-W708 CW-W698 CW-W688 CW-W678 CW-W668

I suspect that
?strsplit
might help you and you can follow the link to regular expressions or do
?regexp
for enlightenment on the wonders of regular expressions.
As another poster has mentioned you can of course use substr() in this
case but regular expressions enable you to do far more.
i haven't tried any of other solution suggested in other posts yet.
thanks for your reply.
