The following node is available in the Open Source KNIME predictive analytics and data mining platform version 2.7.1. Discover over 1000 other nodes, as well as enterprise functionality at http://knime.com.
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 Number) to the R server while missing values in all other types of columns are sent as NA.
R installation:
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.
