Doubt about pattern

Hoi Marcelo,

files <- dir(pattern="*.sens")

but it includes all of the files that have "sens", independent of they be
in the end or in the middle of the name of the file.

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
