R Basics - Descriptive Statistics and Correlation with R, Expandar and Psych packages
Here we use Expandar and psych package to do descriptive statistics, which I assume will be in the survey context. Apologies for not going through the math. I probably would... not have time to do it as this is a quick class to help people who are new to this to get started.
The materials and the R script can be found here
