FSK-Lab support the execution of models created in the R statistical computing language ( For convenience some bundles with preconfigured R are included in the FSK-Lab update-site. You can pick either the 32 or 64 bit version depending of your operating system. If you already have R installed on your system and you prefer to use that version, do not check either of the options. The bundles are named:

  • R 3.4.4 for 64-bit Windows
  • R 3.4.4 for 32-bit Windows

Important: Using the packaged R bundle will create a new folder (“.fsk”) in the local user folder to save automatically installed R librariesIn case this causes conflicts with your local R installation, remove the .fsk folder and make sure, there is no reference to it in the .Rprofile file (found in documents).

Click Next.

Note: Using an existing R installation in FSK-Lab

If you already have pre-configured R in your system and want to use this one, do not check this option. If you want to use your existing R installation together with FSK-Lab it is necessary to configure it, so it works well with FSK-Lab.

First three R packages need to be installed in your existing R installation. These can be easily installed in an R console with the command: install.packages(c('Rserve', 'miniCRAN','svglite')).

Second, The path to R needs to be set in the KNIME software. For that you go to “File -> Preferences -> KNIME -> FSK-Lab” and provide the path to the local R folder that holds a “bin” folder with the R.exe.

Note: In newer versions of FSK-Lab, there is also the option to set the name of a Conda ( environment containing an r-base package. If you have Anaconda or Miniconda installed you may set up an R environment to be used by FSK-lab.
