Open in R, wrong error message? #2

Closed niederle closed 9 years ago

niederle commented 10 years ago

If Rserve is not running (tds-rserver-2 or localhost) this error is thrown by the R plot node and R snippet node:

ERROR R Plot Execute failed: Could not connect to R. Probably, the R-Server is not running. Here's what you need to do: 1) Check what R-server-host is configured in your Knime preferences. 2) If your host is set to be 'localhost' start R and run the following command library(Rserve); Rserve(args = "--vanilla")

That's fine, but in case of the Open in R node this error is thrown? ERROR Open in R Execute failed: spawning of R-process failed

Shouldn't it be the same? ...and wouldnt it be nice to have Open in R be executable without any server running???? It is just local anyway!!?

OpenInR should be integrated into the Snippet and Plot nodes.
