opttest

Optionally test code depending on environment variable.

A convenience wrapper to run code based on whether an environment variable is defined.

opttest(
  expr,
  testname = NULL,
  testvar = "ENABLE_statnet_TESTS",
  yesvals = c("y", "yes", "t", "true", "1"),
  lowercase = TRUE
)

`expr`	An expression to be evaluated only if `testvar` is set to a non-empty value.
`testname`	Optional name of the test. If given, and the test is skipped, will print a message to that end, including the name of the test, and instructions on how to enable it.
`testvar`	Environment variable name. If set to one of the `yesvals`, `expr` is run. Otherwise, an optional message is printed.
`yesvals`	A character vector of strings considered affirmative values for `testvar`.
`lowercase`	Whether to convert the value of `testvar` to lower case before comparing it to `yesvals`.
