When students submit R scripts as homework, they will probably be required to read in some data, perform some analysis and create some plots.

Many times, students use relative paths incorrectly, or use absolute paths. This prevents their code from running on our machines. This app was written in the spirit of getting students to write code that others can run.

To try out the app, you can work with the two solution templates installed with the package. It will use whatever your current working directory as the working directory, so do make sure you have write-access to it.
