The “detectCores” Function in R

• Package: parallel

• Purpose: Detect the number of CPU cores available for parallel processing.

• General class: Parallel computing

• Required argument(s): None

• Notable optional arguments:

• logical: A logical value specifying whether to detect logical cores (default is TRUE).

• Example:

• # Load the parallel package
  library(parallel)
  
  # Detect the number of CPU cores
  num_cores <- detectCores()
  
  # View the number of cores
  print(num_cores)

• In this example, we load the parallel package and use the detectCores function to determine the number of CPU cores available for parallel processing. The result is stored in num_cores, which is then printed to the console to display the number of cores detected.
