Load the values of all available targets.

Shorthand for tar_load(everything()) to load all targets with entries in the metadata.

tar_load_everything(
  branches = NULL,
  meta = targets::tar_meta(store = store, fields = -tidyselect::any_of("time")),
  strict = TRUE,
  silent = FALSE,
  envir = parent.frame(),
  store = targets::tar_config_get("store")
)

Arguments

branches

Integer of indices of the branches to load for any targets that are patterns.

meta

Data frame of target metadata from tar_meta().

strict

Logical of length 1, whether to error out if one of the selected targets is in the metadata but cannot be loaded. Set to FALSE to just load the targets in the metadata that can be loaded and skip the others.

silent

Logical of length 1. Only relevant when strict is FALSE. If silent is FALSE and strict is FALSE, then a message will be printed if a target is in the metadata but cannot be loaded. However, load failures will not stop other targets from being loaded.

envir

R environment in which to load target return values.

store

Character of length 1, directory path to the data store of the pipeline.

Value

Nothing.

Examples

if (identical(Sys.getenv("TAR_EXAMPLES"), "true")) { # for CRAN
tar_dir({ # tar_dir() runs code from a temp dir for CRAN.
tar_script({
  library(targets)
  library(tarchetypes)
  list(
    tar_target(y1, 1 + 1),
    tar_target(y2, 1 + 1),
    tar_target(z, y1 + y2)
  )
}, ask = FALSE)
tar_make()
ls() # Does not have "y1", "y2", or "z".
tar_load_everything()
ls() # Has "y1", "y2", and "z".
})
