Check your package with real CRAN default environment variables and check strategy

check_as_cran(
  pkg = ".",
  check_output = tempfile("check_output"),
  scratch = tempfile("scratch_dir"),
  Ncpus = 1,
  as_command = FALSE,
  clean_before = TRUE,
  open = FALSE
)

Arguments

pkg

pkg directory to check

check_output

Where to store check outputs. Default is a temporary directory

scratch

Where to store temporary files (cleaned after). Default is another temporary directory

Ncpus

Number of CPU used to build the package

as_command

Whether to run the check as Linux command line, instead of directly in R

clean_before

Whether to delete the previous check_output

open

Whether to open the check dir at the end of the process

Value

An object containing errors, warnings, and notes.

Details

When you send your package on CRAN, there are multiple options set before running the checks. Here we use the CRAN settings and way of managing incoming packages used for Linux in this function check_as_cran().

Scripts and options used are directly issued from the GitHub mirror repository of the CRAN machines: https://github.com/r-devel/r-dev-web/tree/master/CRAN/. Although check_as_cran() should run on any OS, it will run CRAN parameters originally set up for Linux machines.

In the check_output, you will get the same outputs, in the same format as used by CRAN, for the pre-test of incoming packages.

Examples

if (FALSE) {
# This runs a check of the current package
# Directory to store the check outputs
check_output <- tempfile("example")
# Check the current package
check_as_cran(check_output = check_output)
# Open directory with all outputs
utils::browseURL(check_output)
}
