What is the easiest way to call 'R' functions from inside Java code. Google search indicates several different approaches, it's a bit confusing and i'm no R expert. Easy = anything that doesn't involve many other dependencies that have to downloaded or learnt, minimal coding/effort, works on Windows, and gets the job done.

Have you tried looking at the R mailing list? http://r.789695.n4.nabble.com/ I know I've had a hard time searching for things related to R on Google because of its one character name. Don't even get me started on searching for tickets to see the band !!!

The easiest way I've found to get information for R is to use http://www.rseek.org which is a metasearch site for R related topics.

Few methods I found. One was Omegahat's R-Java package for R. The have a good whitepaper on using it with examples. It requires a local install from a zip file. Another method is using the rJava package which should be able to be loaded from the R command line with install.packages("rJava")
