Hi everyone,

I believe I am not the first one to have this problem but couldn't find a
relevant thread on the list.

Say I have a string (actually it is the whole column in a data frame) in a
format like this:

test<- 'AF14-485-502-89-00235'

I would like to split the test string and keep the last part. I think I can
do the following

sub('.*-.*-.*-.*-(.*)','\\1', test)

to keep the fifth part of the string. But this won't work if other strings
have more or fewer parts separated by '-'. Is there a general way to do
it?
Thanks.

Jun
