R connection problem for MPI.CBG HCT tools

[agiani99]

Hi all,
trying to run Dose Response (R) node from MPI, with R normally set and RServe running quietly for other plotting R script, I got the following error just for this node:

Configure failed (ForbiddenClassException): de.mpicbg.knime.scripting.core.rgg.wizard.ScriptTemplate

Any hint for me? I was running KNIME v.4.6.3

Best regards
Andrea

@agiani99 could you give us more details? Did this ever work? What R package were you using? Did you use the community nodes or the ‘official’ R nodes (KNIME Interactive R Statistics Integration – KNIME Community Hub) (I would recommend the official ones).

What R version are you using (check version of R packages in KNIME – KNIME Community Hub)?

Sorry mlauber71 for late answer:
R version is 3.6.1
Rserve version is 1.7-3.1

@agiani99 you will need at least Rserve version 1.8-6. Also R itself is now on a higher number.

R integration: Cannot install Rserve

@ehsanT what you should do is make sure RServe does run under R / Studio alone and will be started when library(“Rserve”) is called. Then you could tray the integration into KNIME.

The latest Version 1.8-10 should be available as a Windows binary so there would be no need to compile: https://CRAN.R-project.org/package=Rserve For Windows: install.packages("Rserve", repos = "h…
