Hi I did not notice any answer to your question so I try. After studying docs and other responses to similar question I deduct that chid.var and alt.var are mixed together and new data frame is being build with chid.var and alt.var combination as new row names. As the combination is not unique this operation results to error.
But I may be completely wrong.
