Tests for Write Access
write_access.RdActs as a minimal wrapper around file.access(mode = 2) to test whether R has permission to write to files and/or directories.
Arguments
- names
 character vector containing file names. Tilde-expansion will be done: see
path.expand.
Value
Logical vector of length equal to names. NOTE that this
differs from base::file.access() which returns an integer vector.
