Best way to select files based on file extension (writing in r)

Question

How do I select files based on file extension (writing in r)? Tried

list.files (pattern = ".lvm$") 

in order to select lvm files- no joy

Answer 1

You need to escape the "." (as \\.). An unescaped "." means "every character except a new line" in regex.

There's also fs::dir_ls as

fs::dir_ls(data directory, regexp = "\\.lvm$")
