is_file() is a wrapper for base::file.exists() that allows the exclusion
of directories and returning named vectors. is_dir() is a wrapper for
base::dir.exists() that supports vector inputs rather than single strings.
character(0) inputs return FALSE.
Usage
is_file(x, include_dirs = FALSE, use_names = FALSE)
is_dir(x, use_names = FALSE)
Arguments
- include_dirs
If TRUE, return TRUE for any value of x that is a
directory path. If FALSE (default), return FALSE for directory paths.
- use_names
If TRUE, return a logical vector where the names match the
values of the input vector x. Defaults to FALSE.
