Greetings. I'm teaching linear regression this semester and that means I write more functions for my regression support package "rockchalk". I'm at a point now were some fresh eyes would help, so if you are a student in a course on regression, please consider looking over my package overview document here:
http://pj.freefaculty.org/R/rockchalk.pdf That tells how you can grab the test verion, which is now at 1.7.I'm leaving rockchalk on CRAN at 1.6.3, but as the document linked above explains, 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 try to automate them. That's how the regression table function (outreg) started, and difficulties in plotting predicted values for various kinds of regression drive most of the rest. I guess the rockchalk vignette explains all that. If you are interested in that flavor of R, or know other people who might be, spread the word: we are offering a one-week summer course at the University of Kansas. There is a discount for enrollment before the end of the month. The R course is part of our larger Summer Statistical Institute, which has been growing rapidly for the past decade. We've had very popular courses on structural equations modeling and hierarchical models. Here's the more formal announcement. Stats Camp 2013 registration is now in full swing. Last year we had over 300 participants attend 11 different courses. This coming June we have 15 different courses being offered. Please visit our web pages at http://crmda.ku.edu/statscamp for information on the courses, a brief syllabus for each, and registration information. pj -- Paul E.
