Pin Resource

pin(x, name = NULL, description = NULL, board = NULL, ...)

Arguments

Details

pin() allows you to cache remote resources and intermediate results with ease. When caching remote resources, usually URLs, it will check for HTTP caching headers to avoid re-downloading when the remote result has not changed.

This makes it ideal to support reproducible research by requiring manual instruction to download resources before running your R script.

In addition, pin() still works when working offline or when the remote resource becomes unavailable; when this happens, a warning will be triggered but your code will continue to work.

Examples

# define local board
board_register_local(cache = tempfile())
