Dear R-users,

I have found on the list several posts addressing the issue of getting data for
a list of defined files. However, I found nothing about scanning a given folder
and retrieving the list of, let's say, .txt files (I probably used the wrong
keywords). Could someone tell me which posts or function help I should look at?

Thanks in advance

Sebastien,

see ?list.files, especially the 'pattern' argument. For your
particular case it is

list.files(pattern="\\.txt$")

You might want to use the 'ignore.case' argument as well.

?files

and the links therein. Seems like a most obvious keyword to me for asking
about files ...

Cheers,
