R package that automatically uses several cores?

Question

I have noticed that R only uses one core while executing one of my programs which requires lots of calculations. I would like to take advantage of my multi-core processor to

The package future makes it extremely simple to work in R using parallel and distributed processing. More info here. If you want to apply a function to elements in parallel, the future.apply package provides a quick way to use the "apply" family functions (e.g. apply(), lapply(), and vapply()) in parallel.

Example:

library("future.apply")
library("stats")
x <- 1:10

# Single core
  y <- lapply(x, FUN = quantile, probs = 1:3/4)

# Multicore in parallel
  plan(multiprocess)
  y <- future_lapply(x, FUN = quantile, probs = 1:3/4)
