Hello,
Maybe if you change the pattern to
"^lld[A-Z0-9]*\\.dat$"
Hope this helps,

All,
I have the following files in a directory and I would like only a list of those
starting with “lld" and ending with “dat”. I used the following and it gives
me the lld files
list.files(path = readpath, pattern = "^lld[A-Z0-9]")
to get just .dat files I tried
list.files(path = readpath, pattern = "^lld[A-Z0-9].dat$”) but nothing is
returned
below is a dput from the first command. $ is an end of line anchor correct?
What am I doing wrong?
Best,
Glenn
