Calling R from Scala sbt projects using rscala

In the previous post I showed how the rscala package (which has replaced the jvmr package) can be used to call Scala code from within R. In this post I will show how to call R from Scala code. I have previously described how to do this using jvmr. This post is really just an update to show how things work with rscala.

Calling Scala code from R using rscala

In a previous post I looked at how to call Scala code from R using a CRAN package called jvmr. This package now seems to have been replaced by a new package called rscala. Like the old package, it requires a pre-existing Java installation. Unlike the old package, however, it no longer depends on rJava, which may simplify some installations. The rscala package is well documented, with a reference manual and a draft paper. In this post I will concentrate on the issue of calling sbt-based projects with dependencies on external libraries (such as breeze).
