Environment variables useful for package development #298

Open maurolepore opened 2 years ago

TESTTHAT, example:

is_testing <- function() {
  identical(Sys.getenv("TESTTHAT"), "true")
}

R_CMD, example:

skip_if_R_CMD_check <- function() {
  if (!nzchar(Sys.getenv("R_CMD"))) {
    return(invisible(TRUE))
  }

  skip("Not run in R CMD check")
}

Worth noting that the default GH Action for running R CMD CHECK (r-libs) uses rcmdcheck::rcmdcheck, which appears to still trigger the is_testing function stubbed above.
