Check whether code runs directly, or from within a function

is_run_directly() reports whether the code runs directly in the global environment, or from within a function call. Use it during development and debugging. A function can then behave one way when you run it directly, and another way when a larger analysis plan calls it.

Usage

is_run_directly()

Value

A logical value. TRUE means the code runs directly, from the global environment. FALSE means the code runs from within a function call.

vignette("plnr"). Its "Debugging Tools" section calls is_run_directly() inside an action function, to load data and argset while you develop that function.

Examples

# When run directly
is_run_directly()  # TRUE
#> [1] FALSE

# When run from within a function
test_fn <- function() {
  is_run_directly()  # FALSE
}
test_fn()
#> [1] FALSE
