The function takes a path and changes the current working directory to the path. If the directory specified in the path does not currently exist, it will be created.
Arguments
- base
a character string with the base path to the directory. This is required.
- pre
an optional character string with the prefix to add to the base path. Non character strings will be coerced to character class.
- num
an optional character string, prefixed by
pre
. Non character strings will be coerced to character class.
Details
The function has been designed to be platform independent,
although it has had limited testing. Path creation is done using
file.path
, the existence of the directory is checked using
file.exists
and the directory created with dir.create
.
Only the first argument, is required. The other optional arguments
are handy when one wants to create many similar directories with a common base.
