4.1 Open your assignment RStudio project
In a previous tutorial it was suggested you set up a working root directory called “BIOL202_assignments” to host all your assignment work. You may have also created sub-directories, one for each of the three assignments. Regardless, in your root “BIOL202_assignments” directory locate the RStudio project file (it has a “Rproj” extension in the filename), and open it by double-clicking it.
