Optionally test code depending on environment variable.

Description

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

Usage

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

Arguments

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.
