drake (version 4.4.0)

readd: Function readd

Description

Read a drake target object from the cache. Does not delete the item from the cache.

Usage

readd(target, character_only = FALSE, path = getwd(), search = TRUE,
  cache = drake::get_cache(path = path, search = search, verbose = verbose),
  verbose = TRUE)

Arguments

target

If character_only is TRUE, target is a character string naming the object to read. Otherwise, target is an unquoted symbol with the name of the object. Note: target could be the name of an imported object.

character_only

logical, whether name should be treated as a character or a symbol (just like character.only in library()).

path

Root directory of the drake project, or if search is TRUE, either the project root or a subdirectory of the project.

search

logical. If TRUE, search parent directories to find the nearest drake cache. Otherwise, look in the current working directory only.

cache

optional drake cache. See codenew_cache(). If cache is supplied, the path and search arguments are ignored.

verbose

whether to print console messages
