I am trying to find an efficient way to select certain text files from a
folder with thousands of text files. I used file.list function with a
specific "pattern" to obtain 70 files for each of the i's in 1:100. Next, I
need to select some files from this list of 70 files. The files to be
selected do have a unique "pattern" in their file name. However, I cannot
use list.files function because it looks for a specific path. Any help is
appreciated.
Thanks in advance.

natfiles<- list.files(path=files, pattern= "_natrain.csv", full.names=TRUE
