Allows execution of R commands on an R server. The entire data
(compatible to int, double, and String types) is
transfered to the R server which then executes a series of R commands
entered in the dialog. Each column can be accessed by the name provided
in the input data table. The output has to be assigned to a variable
named R. Missing values are supported, that is, missing
values in numeric columns are transfered as
NaN (Not a

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.
