CAS RPM: Installing & running Rattle in RStudio

At the Ratemaking and Product Management (RPM) seminar of the Casualty Actuarial Society (CAS) in San Diego last month, Linda Brobeck, Peggy Brinkmann, and yours truly gave a concurrent session on a machine learning technique called decision tree analysis. See the DSPA-2 session -- and other sessions -- at this link. Technical issues precluded showing the video of  installing and running Rattle within RStudio. Thus this post.

As Peggy notes, installing and running Rattle takes only three "commands" in R:

  install.packages("rattle", dependencies=c('Depends', "Suggests"))

  library(rattle)

  rattle()

Although not necessary, the "Suggests" option above can avoid Rattle's annoying requests for more packages as you click through its GUI; the downside is the time to download and install about 900 packages. Below ("Read more >>") is a link to a video of me running through the three lines above:
