At the very bottom of the page, you should see the "raw" list of files and directories. Sometimes I upload things and forget to create "links" for them in this README file. If I forget, you can still find what you need at the bottom.
As a joke, I used to call this "StatsRus", but I stopped because it seemed presumptuous to make "me" part of "us". But I still think it was a funny title.
These are things you can actually run and get smart from. The one on barplots is so incredibly awesome, you won't believe it when you see it. As my skills in R programming have improved, I notice these WorkingExamples are becoming a little more elaborate. And you will notice that, when I'm troubled about something, the examples prolifate. Look at plot-plotmath-* for example.
The rockchalk package builds on the little bits of knowledge in Rtips, and it offers some more complete regression-oriented functions to process fitted models into output for papers. Distributed with rockchalk, there is an examples folder, and there are some examples there that might help you understand R programming. In the rockchalk package's install folder, look for files "nowords-*.R" for some R programming insights.
The vignettes from rockchalk are
On September 27, 2013, I was delighted/honored to participate in a Webinar on rockchalk, graciously hosted by Ray DiGiacomo, president of the OCRUG. The screen cast of the recording is in Quicktime format, in the file Webinar-OCRUG-20130927/rockchalk_2013-09-27.zip which you can download, decompress, and watch (over and over!). The slides themelves are in the same directory, in a file called rockchalk-slides.pdf.
There are 2 R files to note in the same directory.
The Sweave process that generates the slides also creates an R code file that one could use to replicate the analysis.
I may make revisions to those slides for other presentations, so the slides that were used on Sept. 27 will remain in the Webinar folder here, while the changing version will be in the location mentioned in the Webinar itself, which was in my "guides" directory, under Rcourse/rockchalk-2013.
Most of these are LaTeX, many are Sweaved to combine R with the document. I'm uploading everything here, the source code, anything necessary to reproduce the pdf lectures. I'm offering this as a free service, free for reuse to anybody as long as they acknowledge where they took the material.
If you are just beginning with R, I have prepared some very basic presentations for a group of undergraduate interns and I think they will help you get started. Please look at http://pj.freefaculty.org/guides/Rcourse/First-R.
During the Stats Camp at University of Kansas, a "camper" asked me for help in learning how to use Sweave. More recently, I've developed some notes on Sweave and Beamer presentations. That materials is now online LyX-sweave-tutorial, which shows the bare minimum steps needed to use Sweave.
I have a "LaTeX Get Started" document in the guides directory (read below). http://pj.freefaculty.org/guides/Computing-HOWTO/LatexAndLyx
I found myself walking through the same installs over and over with Windows users. So I made these screencasts to give people a head start. I don't hold these out as great production quality, but they do reflect a nearly week-long battle with a Windows 8 virtual machine, CamStudio, the hosts audio/video system. Its very tricky to keep the video and audio synced.
On a Windows 8 system, this demonstrates the R installation, basic usage, as well as the importation of an Excel spreadsheet using the gdata package's read.xls function, with the support of ActivePerl. Part 2 in this series discusses better editors for code preparation: http://youtu.be/lNlJFEpdytc
Installing and using programmer's file editors to interact with an R session. Demonstrates the installation, configuration, and usage to offer the viewer a clear view of what these editors offer. This is important because the editor provided with R for Windows does not offer conveniences for coders. This is the second presentation in a series, please view the first one, StartR 01, which is about installing R, ActivePerl, and R packages. http://youtu.be/pmK9bWG1ftk
