furrr (version 0.2.3)

future_options: Deprecated furrr options

Description

future_options() has been deprecated in favor of furrr_options() as of furrr 0.2.0.

Usage

future_options(
  globals = TRUE,
  packages = NULL,
  seed = FALSE,
  lazy = FALSE,
  scheduling = 1
)

Arguments

globals

A logical, a character vector, a named list, or NULL for controlling how globals are handled. For details, see the Global variables section below.

packages

A character vector, or NULL. If supplied, this specifies packages that are guaranteed to be attached in the R environment where the future is evaluated.

seed

A logical, an integer of length 1 or 7, a list of length(.x) with pre-generated random seeds, or NULL. For details, see the Reproducible random number generation (RNG) section below.

lazy

A logical. Specifies whether futures should be resolved lazily or eagerly.

scheduling

A single integer, logical, or Inf. This argument controls the average number of futures ("chunks") per worker.

• If 0, then a single future is used to process all elements of .x.

• If 1 or TRUE, then one future per worker is used.

• If 2, then each worker will process two futures (provided there are enough elements in .x).

• If Inf or FALSE, then one future per element of .x is used.

This argument is only used if chunk_size is NULL.

Examples

# NOT RUN {
future_options()
# }
