Create the path to a temporary file inside drake's cache.
drake_tempfile(path = NULL, cache = drake::drake_cache(path = path))
Path to a
drake cache. See
This function is just like the
tempfile() function in base R
except that the path points to a special location inside
This ensures that if the file needs to be copied to
persistent storage in the cache,
drake does not need to copy across
physical storage media. Example: the
"diskframe" format. See the
"Formats" and "Columns" sections of the
drake_plan() help file.
Unless you supply the cache or the path to the cache
drake will assume the cache folder is named
.drake/ and it is located either in your working directory or an
ancestor of your working directory.
