Hi folks,
I'm interested in finding files by matching both filenames and
directories via regex. If I have:
dir1_pat1/file1.csv
dir2_pat1/file2.csv
dir2_pat1/file3.txt
dir3_pat2/file4.csv
I would like to find, for example, all csv files in directories that
have "pat1" in their name:
dir1_pat1/file1.csv
dir2_pat1/file2.csv
> list.files(path = ".", pattern = ".*pat1/.*\\.csv", recursive = T)
character(0)
> list.files(path = ".", pattern = ".*pat1/.*\\.csv", recursive = T,
full.names=T)
character(0)
> list.files(path = ".", pattern = ".*\\.csv", recursive = T, full.names=T)
[1] "./dir1_pat1/file1.csv" "./dir2_pat1/file2.csv" "./dir3_pat2/file4.csv"
> list.files(path = ".", pattern = "pat1", recursive = T, full.names=T)
character(0)
I think list.files just runs the regex pattern against the file names,
not the full path. I tried full.names=T, but it still matches against
the file name only.
Suggestions are greatly appreciated.
Thank you,
Allie
