R Projects and Folder Structure

An R project is a project-specific workspace. In RStudio, a project is usually represented by a file ending in `.Rproj`. Opening the project file sets the working context for the study or course exercise. This is important because many errors in R occur when the user is working in the wrong folder. If R cannot find a file, the problem is often not that the file does not exist, but that R is looking in a different location.
