R is an opensource powerful programming language suited to mathematical and statistical computing, analysis and graphics.
RStudio provides a convenient interface for using R. Both R and RStudio are free.
From “Preferences” set the default folder to your documents or other convenient folder.
I set mine to my Dropbox folder.
After you have set the folder, quit and reopen RStudio.
A project is a folder where you can keep data, code and documents together.
You can have several different projects and set R to start up differently for each project. Projects allow you to keep your files organised, and let you customise how R works.
If you use R for other classes, your seminar or other purposes, you can create other projects for those.
Each project will have a separate folder and files to save the data in your environment, your history of code executed in the console, and the way you have R configured.
Make a new project from the Projects menu at the top-right of the screen.
I use the name “portfoliomngt.”
Click “Create Project.”
