Check a distribution function returns valid output and has the correct number of arguments

Check a distribution function returns valid output and has the correct number of arguments

Usage

check_dist_func(func, dist_name, n_req_args = 1, func_eval_min = 0)

Arguments

func

a function.

dist_name

a character string: the name of the distribution function being passed (e.g. "incubation_period")

n_req_args

a single numeric: the number of required arguments

func_eval_min

a single numeric: the lower bound of valid numeric output by the func argument (i.e. the minimum of the acceptable value in the function's codomain). The default is 0 so func must return non-negative values.

Value

TRUE if all the checks pass or an error is thrown if the distribution function is invalid.
