rb3 (version 0.1.0)

rb3.cachedir: rb3.cachedir Option

Description

The rb3.cachedir option is used to specify the directory where cached data will be stored when using the rb3 package. This option allows users to define a custom directory for caching, which can improve performance by avoiding repeated downloads or computations.

Details

Setting the rb3.cachedir Option

To set the rb3.cachedir option, use the options() function and provide the desired directory path as a string. For example:

# Set the cache directory to a custom path
options(rb3.cachedir = "/path/to/your/cache/directory")

Replace "/path/to/your/cache/directory" with the actual path where you want the cached data to be stored.

Viewing the Current Value of rb3.cachedir

To check the current value of the rb3.cachedir option, use the getOption() function:

# View the current cache directory
getOption("rb3.cachedir")

This will return the path to the directory currently set for caching, or NULL if the option has not been set.

Notes

• Ensure that the specified directory exists and is writable.

• If the rb3.cachedir option is not set, the package use a temporary directory (base::tempdir()).

Examples

# Set the cache directory
options(rb3.cachedir = "~/rb3_cache")

# Verify the cache directory
cache_dir <- getOption("rb3.cachedir")
print(cache_dir)

# In this example, the cache directory is set to `~/rb3_cache`, and the value 
# is then retrieved and printed to confirm the setting.
