check_try: Helper function to convert assert statements into checks

Description

Tries to execute an expression. Internally, this is used to see whether assertions fail when checking inputs (i.e. to convert an assert_*() statement into a check). If the expression fails, the error message is returned. If the expression succeeds, TRUE is returned.

Usage

check_try(expr)

Value

Returns TRUE if the check was successful and a string with an error message otherwise.

Arguments

expr

an expression to be evaluated
