Statistics Programs in R

As part of my outreach to the R community, I offer these programs that accomplish tasks that are common in statistical analyses. Explanatory comments are embedded within the programs themselves.

1. Calculating means
2. T-tests for the difference between two means
3. Crosstabulation tables
4. Introductory multiple regression
5. Multiple regression using dummy variables
6. Evaluating multicollinearity with multiple regression
7. Logistic regression

Data sets used with these programs can be found HERE.

Below are the variables and labels for the data sets used in some of my statistics programs.
