pre_check: Pre-check code

In dtkaplan/checkr: Facilities for checking R submissions in tutorials

Description

Checks first whether the code parses. If so, funs the code looking for errors. If any errors are found, a diagnostic message is returned.

Usage

pre_check(user_code, soln_code = "hello")

Arguments

user_code	A character string containing the code to be checked. Note that this is a character string, not a checkr_result. Constructing a checkr_result requires that the code be evaluated, while this function is for pre-evaluation checking.
soln_code	Code, if any, containing a correct solution.

Value

A checkr_result object.

Examples

code <- "lm(mpg ~ hp, data <- mtcars); plot(1:10); x <- 1\n y <- x^2\n\n z = cos(yy * xx^2)"
pre_check(code)
