Functions for lazy-loading knitr caches.

Description

These functions are helpful for loading cached chunks into an interactive session.

Usage

lazyload_cache_dir(
  path = "./cache",
  envir = parent.frame(),
  ask = FALSE,
  verbose = getOption("verbose", FALSE),
  full.names = TRUE,
  ...
)

lazyload_cache_labels(
  labels,
  path = "./cache/",
  envir = parent.frame(),
  verbose = getOption("verbose", FALSE),
  filter,
  full.names = TRUE,
  ...
)

Arguments

path	the path to the cache directory
envir	the environment to load the objects into
ask	if TRUE, interactively ask whether to load each database discovered in path
verbose	if TRUE, display the names of chunk labels being loaded
full.names	use the full name, i.e., include the path, for the chunk label? This argument is passed to list.files.
...	additional arguments passed to list.files
labels	character vector; chunk labels to load
filter	optional function; passed to lazyLoad. When called on a character vector of object names, this function should return a logical vector: objects for which this is TRUE will be loaded.

Details

Use lazyload_cache_dir to load a whole directory of cached objects.

Use lazyload_cache_labels to load and explicit set of cached chunks.

Value

Both functions return NULL, invisibly.
