Description Usage Arguments Value Author(s) See Also

Function for creating a Caching engine with specific behaviors

cachingEngine(base_dir = "./r_caches", tmp_base_dir = tempdir(),
  write_allowed = TRUE, write_on_cache = FALSE, gdevs = list(png),
  eval_fun = parseWithVis, return_handler = withVisHandler,
  populate = TRUE)

`base_dir`	character value . Path to which permanent caches should be written (if applicable)
`tmp_base_dir`	character value. Path to which temporary caches should be written (if applicable)
`write_allowed`	logical. Should the engine allow caches to be written to disk. Defaults to `TRUE`
`write_on_cache`	logical. Should the engine write caches to disk immediately upon creation. Defaults to `FALSE`
`gdevs`	list. A list of graphics device functions to use when caching plots. Defaults to `list(png)`
`eval_fun`	function. The evaluator function to be used when no cache is found. Defaults to `parseWithVis`.
`return_handler`	function. The function to process values returned by `eval_fun`. This function will be called on values returned from `eval_fun` directly and those loaded from cache. Defaults to `withVisHandler` which supports plot caching.
`populate`	logical. Should the engine include existing caches from `base_dir` upon creation. Defaults to `TRUE`
