That's because your pattern is a regular expression and not a Windows/DOS
wildcard. You'll need something like
files <- dir(pattern="\.sens$")
\. matches the dot itself (without the slash it's a wildcard for any
character) and the dollar sign $ matches the end of the filename. So this
way you'll get every file that has 'sens' as its extension
regards,
Paul
