If this is a path name, then 'basename' will work for you:

[1] "BLC.NYSE"

By the way, although a regular expression solutions was asked for
if one expands that to any solution then R does have a function
specifically for this case:

Hi Mark,
do you mean the regex to get the portion of the address after the
final slash? Something like
gsub(".*/([^/]*$)", "\\1", stock, fixed=FALSE)
Cheers

Hi Mark,
stock<-"/opt/limsrv/mark/research/equity/projects/testDL/stock_data/fhdb/US/BLC.NYSE"

If I have the string below. does someone know a regular expression to
just get the "BLC.NYSE". I bought the O'Reilley
book and read it when I can and I study the solutions on the list but
I'm still not self sufficient with these things. Thanks.
stock<-"/opt/limsrv/mark/research/equity/project
It can be done like this with strapply in gsubfn. See home
page at http://gsubfn.googlecode.com . strapply is like
apply except the string to be operated on replaces the
matrix and the regexp replaces the margin number
and the function can be omitted if you are only returning
one item.Its like
Will this do it:

[1] "20.20.20"

[1] "all"

I have a string such as
fileName<-"Agg.20.20.20-all-01".
All I want to do is pull the "20.20.20" and the "all" as strings.
Obviously, they aren't always those values.
The "20.20.20" can be "30.30.30" but it's always after the . which is
next to the second g in Agg and it's always the same len
9 matches
