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)
}
