isExpensiveExampleOk: Conditional checking for expensive examples.

Description

Queries environment variable R_EXPENSIVE_EXAMPLE_OK. Returns TRUE iff set exactly to TRUE. This allows conditional checking of expensive examples in packages via R CMD CHECK, so they are not run on CRAN, but at least on your local computer. A better option than dont_run in many cases, where such examples are not checked at all.

Usage

isExpensiveExampleOk()

Value

• [logical(1)].

Examples

# extremely costly random number generation, that we dont want checked on CRAN
if (isExpensiveExampleOk()) {
  runif(1)
}
