Hi,
#working directory data1 #changed name data to data1.? Added some files in each of sub directories a1, a2, etc.

If you want the names to be group_a, group_b etc.
?names(res)<-paste("group_",gsub("\\d+","",names(res)),sep="")
res[grep("group_b",names(res))]
$group_b

Subject: reading data
Hi,
I post yesterday and you helped me. I have little problem.
At first, I never worked with regular expressions...
The code that you gave me it's ok, but my files are inside the folders a1,a2,a3. I try to explain better.
I have one folder named "data". Inside this folder I have some other folders named "a1","a2","b1",b2",...and inside of each one of that I have some files. I want only the file "mmmmmm.txt" (in all folders I have One file with this name).
The name of the folder give me the name of the group,but I need to read the file inside. And after, have "group_a", group_"b"...because I need to work with this data grouped (and know the name of the group).
Thank you.
