giscoR (version 0.3.1)

gisco_set_cache_dir: Set your giscoR cache dir

Description

This function will store your cache_dir path on your local machine and would load it for future sessions. Type Sys.getenv("GISCO_CACHE_DIR") to find your cached path.

Alternatively, you can store the cache_dir manually with the following options:

• Run Sys.setenv(GISCO_CACHE_DIR = "cache_dir"). You would need to run this command on each session (Similar to install = FALSE).

• Set options(gisco_cache_dir = "cache_dir"). Similar to the previous option. This is not recommended any more, and it is provided for backwards compatibility purposes.

• Write this line on your .Renviron file: GISCO_CACHE_DIR = "value_for_cache_dir" (same behavior than install = TRUE). This would store your cache_dir permanently.

Usage

gisco_set_cache_dir(
  cache_dir,
  overwrite = FALSE,
  install = FALSE,
  verbose = TRUE
)

Arguments

cache_dir

A path to a cache directory. On missing value the function would store the cached files on a temporary dir (See base::tempdir()).

overwrite

If this is set to TRUE, it will overwrite an existing GISCO_CACHE_DIR that you already have in local machine.

install

if TRUE, will install the key in your local machine for use in future sessions. Defaults to FALSE. If cache_dir is FALSE this parameter is set to FALSE automatically.

verbose

Logical, displays information. Useful for debugging, default is FALSE.

Value

An (invisible) character with the path to your cache_dir.
