Phil 2.23.11

7:30 -5:30 VISIBILITY

  • Server Meeting today at 11:15. Don’t see how I can make that
  • Over at site starting at 1:30
  • Setting up rJava: http://www.mumuen.com/2010/10/running-r-in-java-with-jrirjava.html
  • Got the rtest code in the rJava examples directory compiling. It turns out that the CRAN directory has an old version. Sheesh. Updated the maven repo with the version 9 jars. Added R_HOME to the path. Restarting all to register changes… No joy.
  • Following the directions here: http://mithil-tech.blogspot.com/2009/11/r-and-java-jri-via-eclipse.html
    • That worked!
  • Next will be to get R to run in Tomcat: Here’s where I’ll start: http://wiki.cvrgrid.org/index.php/RJava/jri_Setup
  • Useful r packages so far (google “CRAN xx’ for detailed info on the package):
    • sqldf – allows SQL manipulation of tables
    • reshape – for manipulation of data types
    • gwidgets – support for interactive graphics
    • HH
    • rJava – java interaction
    • RServe – R as a webserver
