    This error is a result of the way the model was originally created as opposed to the step in the R script where the model is being converted to PMML format.

    When an input data set is read into the embedded R engine by the Power R node, string variables in the data set can be represented as either Characters or Factors. The default operation for the Power R node is to represent strings as Characters. This operation may be changed by setting the 'InportStringCoercion' parameter on the Optional tab of the Power R node to 'To Factor'.
