Source: R/util_lapply.R

Utility to use different implementations of lapply.

util_lapply(FUN, args, par = TRUE, ncores = NULL)

Arguments

FUN

Function to apply.
args

Named list. Arguments to pass to FUN. The first item (args[[1]]) should be first argument of FUN. This corresponds to the argument X in mclapply, parLapply or lapply.
par

Logical. If TRUE, use multiple cores.
ncores

Integer. Number of cores to use if par = TRUE. If unspecified, defaults to detectCores() - 1.

Examples

util_lapply(
  FUN = rnorm,
  args = list(
    n = rep(x = 5, times = 5),
    mean = 100,
    sd = 15
  ),
  par = FALSE
)
