I'm looking for an integration of ImageJ and R. There was a package called RImageJ as referenced in  for previous versions of R (I'm using R 3.1.2 (2014-10-31) -- "Pumpkin Helmet" ) but it isn't available anymore.
Basically what I'd like to try is a region growing algorithm over an image in R. Does anybody know about an updated version of RImageJ or another package allowing this algorithm?.
The Bio7 project is a version of ImageJ which features integration with R, among other improvements.
It is also worth mentioning that the ImageJ2 project has a project under development called scripting-r, which seeks to provide a JSR-223-compliant scripting language built on top of RServe. However, it is not yet functional. Once it is, it will be possible to execute R code as a script from within ImageJ's Script Editor.
Edit 2016-09-26: As of this writing, the SciJava
scripting-r project is now built on Renjin, an implementation of R on top of the JVM. Huzzah!
