Subject: [R-pkg-devel] Parallel processing
*I am building a package a package and one of its functions need parallel
procesing.*
*Then I created the function because my final use are not technical:*
create.cluster <-function()
{
# Calculate the number of cores
no_cores <-parallel::detectCores() - 1
# Initiate cluster
cl <- parallel::makeCluster(no_cores)
return(cl)
} # create.cluster <-function()
*Then the final use need to execute:*
cl <- create.cluster()
Commands
parallel::stopCluster(cl);
*When preparing my package with "R CMD check --as-cran mypackage" the
following error occurs:*
*Error in .check_ncores(length(names)) : 3 simultaneous processes spawned*
*I know the limit of cores is 2 for package check and my laptop has 4, I
believe this is the error cause.*
*How I would fix this error?*

*Thank you*
