Hi Mauro,

On Mac, you will also need the "Cairo" package in addition to Rserve installed in R.

Cheers,

Dears,

I’m trying run the 01_Example_of _R_of_Snippet (from the server examples ) on Mac (Mojave, 10.14.2) but when execute the R View(Workspace) node i get this error:

Error: no active device and default getOption(“device”) is invalid
Error: cannot shut down device 1 (the null device).

Some ideia ?

Thanks,

Andrés.

@afflorezr,
do you have cairo installed? Check the KNIME-R preferences it should tell you that cairo might be missing. Note that installing cairo on mac requires you to install XQuartz
