The “plan” Function in R

• Package: future

• Purpose: Configures a future backend plan for parallel processing.

• General class: Parallel computing

• Required argument(s):

• strategy: The strategy for parallelization.

• Notable optional arguments:

• workers: Number of workers to be used.

• Example:

• # Load the future package
  library(future)
  
  # Plan a future backend with multicore strategy
  plan(multicore)
  
  # Now execute parallel code using futures
  values <- future_map(1:10, ~ sqrt(.x))
  
  # Print the result
  print(values)

• This example demonstrates how to use the “plan” function from the future package to set up a future backend with a multicore strategy. The “strategy” argument specifies the parallelization strategy and the “workers” argument determines the number of cores used for the calculations.
