...ngs I perceive in R's summary function. The package is not coordinated with any particular textbook and should help in any class in which students are expected to estimate regression models, summarize them in professional-looking tables, and conduct various follow up diagnostics. Highlights: plotSlopes & testSlopes: draw "simple slopes" graphs and conduct hypothesis tests for moderator variables. plotCurves: an attempt to provide a "termplot" replacement that allows plots that incorporate mediators. plotPlane: a wrapper for persp to plot regressions in 3d (similar to s...

...you can download the test version from our local repository called "kran". I have been making new packages every 3 days or so. If you are a github user, you can clone a copy of the source if you like (http:// The functions that have gotten the biggest workover are predictOMatic, newdata, plotSlopes, plotCurves, and testSlopes. If you just install the package and run those examples, you will be able to tell right away if you are interested in trying to adapt these to your needs. Generally speaking, I watch the students each semester to see which R things frustrate them the most and then I tr...
