How can I see R console in KNIME

I'm using RPlot node in KNIME and its showing some warning saying that see R console for further details but I don't know where is R console in KNIME.

Open its views.

which views? Can you explain it a bit plz

I hope this helps. (I forget to add. To see the warnings, you need the warnings() command in R, which prints it to the standard output. message prints to standard error.)

Cheers, gabor
