Hi,
Not sure this is what you need, but what about list.files()?
It can get you all the files from a given folder, and you could then
work this list with regular expressions for example.
HTH,

Dear Michael,
Thanks for your codes. However, lapply does not work in my case since I've
some files missing in the data (say, the file data101.dat). Do you have any
suggestions on this?? Thank you very much.
You could simply add a test using file.exists() but I'm not sure what
you want to do with the M matrix then -- omit the slice (so the others
are all shifted down one) or fill it entirely with NA's.
Michael
