1 Introduction to CADStat

2 CADStat and R R is a powerful and free statistical package [http://www.r-project.org/]

3 R capabilities R provides flexible plotting algorithms & libraries for running virtually any statistical analysis… …but R is run at the command line, so there’s a steep learning curve.

4 Java GUI for R (JGR) A Graphical User Interface (GUI) has been developed for R, which provides a point-and-click interface for some basic R functions.

5 CADStat Point-and-click interfaces for statistical tools useful in causal analysis Rendering of analysis results in browser window Additional help files CADStat adds several tools to JGR:

6 To your computers… Launch JGR & set up CADStat add-on.

7 Make sure “loaded” & “default” are checked for CADStat. [you should only have to do this step the 1 st time you run CADStat]

8 Set Working Directory.

9 JGR/CADStat: A gentler introduction to R Installing packages Setting up a workspace Loading data Managing data in your workspace JGR provides point-and-click tools for basic R functions:
