A Quick Course in R

This is a quick introduction to get you started using R without assuming a lot of programing experience.

Download the PDF slides and also the text file quick-course-in-R.R or quick-course-in-R-win.txt so you can easily copy and paste the R commands in the tutorial. Save the file example.txt that you need for the Importing Data section.

To practice some of the skills covered in this tutorial, please consider a short R Lab. You will need the data file R_lab.csv.

Please email me at yorgovd@pfw.edu with comments and suggestion for improvements or typos. Cheers!
