R_Interactive Error

KNIME Extensions
1

Hi all,

I am trying to execute simple R codes in R Interactive Snippet, but getting error saying :

R cannot be intialized.
null
 
after execution getting another error:
 
Error RController
 
Can someone tell what could be the problem?
Thanks in advance!

I would need the full stack trace to investigate the problem, also see the FAQ for problems with the new interactive R integration.

Hi Gabriel,

same here. The FAQ seems to refer to a different problem.

Thanks for reporting this problem. We are working on a fix that will be released with one of the next KNIME Desktop versions. Thanks again!
