Does the file exist?

Checks to see if the input files exist.

Usage
assert_all_are_existing_files(x, severity = getOption("assertive.severity", "stop"))
assert_any_are_existing_files(x, severity = getOption("assertive.severity", "stop"))
is_existing_file(x, .xname = get_name_in_parent(x))
Arguments
x
Input to check.
severity
How severe should the consequences of the assertion be? Either "stop", "warning", "message", or "none".
.xname
Not intended to be used directly.
Value

is_existing_file wraps file.exists, showing the names of the inputs in the answer. assert_*_are_existing_files return nothing but throws an error if is_existing_file returns FALSE.

Note

Trailing slashes are removed from paths to avoid a lot of false negatives by the underlying function file.exists.
