Hello,
when I use list.files with recursive = TRUE and all.files = TRUE, R returns
a list of strings/paths.
>From all those strings I want to keep only the ones starting with a .
I tried using grep to achieve that. However, the problem is that because of
the recursive list.files parameter,
for some files beginning with a . there is a path attached. I think it is
not as simple as it looks because all files
end with . something. .xlsx or .txt or .r...
files <- list.files("~", recursive = TRUE, all.files = TRUE)
files
/XXX/ZZZ/.R_history
/XXX/ZZZ/AAA/Script.r
/XXX/ZZZ/BBB/test.xlsx
/XXX/ZZZ/CCC/.xyz
files <- files[grep("^.*$", files)]
I want grep to return only the following to lines:
/XXX/ZZZ/.R_history
/XXX/ZZZ/CCC/.xyz
Any ideas on how to solve that issue?
Cheers
syrvn
