future_options()
has been deprecated in favor of furrr_options()
as
of furrr 0.2.0.
future_options(
globals = TRUE,
packages = NULL,
seed = FALSE,
lazy = 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 logical. Specifies whether futures should be resolved lazily or eagerly.
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
.
