New version Knime r snippet does not show old R code!!!

[hello_knime]

Hi,

I have upgraded to the latest version of Knime 3.1.0 from 2.1. As I  imported my old work-flow to my new Knime,  all my codes written in R snippet vanished!!! What is going on?

Please help!

Thanks,

Shari

Hi Shari,

did you receive any error messages when loading the workflow?

Also, could you please check whether the workflow still loads correctly in 2.12?

Thank you very much, 

Jonathan

Hi,

Thanks for your reply. I get the following error which is not related to R snippet node.

It seems you haven't install the R extension. You can install it via File -> Install KNIME Extensions...
