Re: [R] grep fixed (?) in 2.14
Hi, . and * both mean something different in regular expressions than in command-line wildcards. You need: grep(.*\\.R$, scripts2source) which parses to .- any character *- any number of times \\. - an actual . escaped as R requires R - the R denoting a script $ - at the end of the string grep(.*\\.R$, scripts2source) [1] 1 3 4 6 7 8 9 10 11 12 15 16 17 18 19 21 22 23 25 26 27 Sarah On Thu, Nov 3, 2011 at 8:54 AM, Stephen Sefick sas0...@auburn.edu wrote: #This is probably due to my incomplete understanding of grep, but the below code has been working for some time to #search for .R with anything in front of it and return a list of scripts to source.

your syntax is wrong, you need: scripts2source[grep(*\\.R$, scripts2source)] Notice the '\\.' to escape the special meaning of '.', and the $ to anchor to the end of the line.

Re: [R] grep fixed (?) in 2.14
That did the trick. I have read about regular expressions often, and sometimes I get them right and sometimes I don't. Is there a good reference resource that anyone could suggest? Thanks for all of the help.
