parallelLapply

Parallel versions of apply-family functions.

Description

parallelLapply: A parallel lapply() version.
parallelSapply: A parallel sapply() version.
All functions are simple wrappers for parallelMap().

Usage

parallelLapply(xs, fun, ..., impute.error = NULL, level = NA_character_)

parallelSapply(
  xs,
  fun,
  ...,
  simplify = TRUE,
  use.names = TRUE,
  impute.error = NULL,
  level = NA_character_
)

Arguments

`xs`	(`vector` \| `list`) `fun` is applied to the elements of this argument.
`fun`	`function` Function to map over `xs`.
`...`	(any) Further arguments passed to `fun`.
`impute.error`	(`NULL` \| `function(x)`) See `parallelMap()`.
`level`	(`character(1)`) See `parallelMap()`.
`simplify`	(`logical(1)`) See `sapply()`. Default is `TRUE`.
`use.names`	(`logical(1)`) See `sapply()`. Default is `TRUE`.

Value

For parallelLapply a named list, for parallelSapply it depends on the return value of fun and the settings of simplify and use.names.
