I am using R source node for my workflow, but when I configure it it shows the following error
**ERROR:** Could not execute internal command.ERROR: R evaluation failed.: "sapply(ls(),function(a)class(get(a,envir=globalenv())))"ERROR: R evaluation failed.: "sapply(ls(),function(a)class(get(a,envir=globalenv())))"ERROR: eval failed
I tried to search for the error but no results were found then I looked into the KNIME forum if someone had the same error but again could not found it.
I have attached the 2 images , first image is with the error in configuration window
And the second one with the workflow where R source node stops at just 30% and did not complete the execution.
To use the R source node I already have KNIME Interactive R Statistics Integration extension installed.
Does anyone know what is the problem here ? Your help is very much appreciated.
