R

R is an excellent program and language for statistical analyses, and I highly recommend it. For further information see:

Projects

Jmisc

Jmisc is a collection of miscellaneous functions I wrote that eventually grew large and interdependent enough it made sense to organize into a package, if only for my own sanity. It also provides a nice way to document exactly what (I think) the code does and how it does it. If it ever grows large enough to be broadly useful, I will submit it to CRAN. It is currently licensed under GPLv3.

Currently the most interesting function is StackedDots. If the package is installed, example(StackedDots) will provide examples.

Installation

Jmisc, is now hosted on Google Code. You can find it's project page here: http://code.google.com/p/jmisc/

To install Jmisc, you can install the latest development version by running:

source("http://joshuawiley.com/R/Jmisc_devel_installer.R")

or by going to the Google project page and downloading the latest version as a tar ball and installing that. Jmisc contains strictly R code, so no special compilers should be necessary.  However, should you run into problems building from source, please see the official R manual here on setting up and using the tools necessary to compile your own R packages.

Before uploading a development version, I at least make sure it passes R CMD check. For the very latest edits, you can use subversion. Note that this may not pass R CMD check. I often write functions first and create documentation later.

I am going to try to post Windows binary files for the latest stable version of R, but as these are OS and R version specific, they are more likely to have problems than the source code.

R2HTML

I have recently joined the development team of the R2HTML package. There is a lot of great work there already. I am particularly interested in expanding functionality with Sweave, especially support of a verbatim mode for instructional purposes. For more information and the latest updates, see the R-forge project page.
