Lab 2: R basics
This module contains a PowerPoint file, some R code, and a data fle.
PowerPoint
Stuff that's covered: View your data, sort, subset, and recode. Compute descriptive statistics and export the table to Word. Check data for normality (Q-Q plot, Shapiro-Wilks test), and run a simple simulation that shows the effect of sampling error.

R code
My university won't let me post many file types, including those with the .r extension. So I will send you to an external server (Github) where you can download the R code.
