for my scope I'm tryng to use mvOutlier of MVN R library in Knime with the R Snippet Node. To test the correct working I have runned this function in R and in Knime on the same database (the classic iris dataset) .
But there is a strange problem: when I run the R snippet node in Knime with this two command:
2- knime.out <- mvOutlier(knime.in, qqplot = TRUE, method = "quan",label = TRUE)
I obtain exactly the same output PLOT on R but at the same time the R snippet node go to Execution Failed: "ERROR R Snippet 0:829 Execute failed: R evaluation failed".
With this error I cannot view the results on output table of R snippet node.
Thank you for any supports or suggestions
