In order to get the R nodes running, you have to install the R-project first, see www.r-project.org. Also the R server which responds to R commands has to be installed and running, see http://www.rforge.net/Rserve/.
Also make sure that you have the latest available or compatible R-project version at hand. For Windows you may download an R server for your R-project version. All other operating systems require the most recent clients (R-project installation). We offer downloads of current versions of R and Rserve that are compatible with KNIME on our website. Please note that in the current version the R server needs to be restarted from time to time. If an R node hangs, interrupt the R server and restart it. Warnings and errors are printed in the R server window.
