check_try {scoringutils} | R Documentation |
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)
Arguments
expr |
an expression to be evaluated |
Value
Returns TRUE if the check was successful and a string with an error message otherwise.
