library()ing packages didn’t work, and that’s now fixed. This was because callr::r() needed package=TRUE.
Student submissions are now run in a separate R session. This will ensure that student submissions are run with the same search path that they are using on their local machines.
A suppress_warnings argument was added to calcGradesForGradescope. Now you can choose whether or not warnings should be fatal when running student submission scripts.
Second, more flexibility in specifying the test visibility has been added. Students can see the test results before the submission deadline, after the submission deadline but before the publish date, after the publish date, or never.
Fixed the multiple assertions bugs in calcGrades and calcGradesForGradescope. If one test had multiple calls to some expect function, all but the first would be ignored. Now, they are all tested, and full points are awarded if and only if they are all true. Thanks to Al Fischer of WCU for spotting this!
Two bugs in the vignette were fixed as well. data.csv needed to be in the local directory from where calcGrades is called, and there shouldn’t be any setwd() calls in the test file.
calcGradesForGradescope function, which helps grade assignments on the Gradescope platformusing_gradeR_with_Gradescope a vignette for helping with the set up of Gradescope’s autograderfindGlobalPaths, which searches student submissions for the very bad global/machine-specific file pathsfindBadEncodingFiles, which searches student submissions for the very bad non-UTF-8 charactersverbose argument to calcGrades, so you can see which file is being ran in real time-warnings that get triggered by running student submission can now be ignored.
-added a vignette with a fully-worked example
source call inside tryCatch function, so that broken submissions don’t interrupt calcGrades callFixed bug that prevents an odd number of submissions!
Made the columns of the returned data frame a little prettier.
First release!
