Deprecated furrr options



As of furrr 0.3.0, future_options() is defunct in favor of furrr_options().


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



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


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.


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.


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.
