Knime Server Add Table to R Error

When executing an Add Table to R node on the knime server I get the following error : Execute failed: Execution of R script failed: Error: unexpected input in "C:\"

The code does not have any syntax of "C:\"

This code does execute properly on the local drive and in the "configure" state.

 

Please advise.

 

Do any of the R nodes run? Are the preferences for the location of R set up properly? 

Other R nodes are working. In fact, this particular node worked until I moved it to knime server.
