Problem: Weighted COA of 3 column file

I have been trying to prepare data tables for RLQ analysis. A weighted COA
of my R table (394 rows, 3 columns) using a file.fcpl produced from COA of
the L table repeatedly fails. Introducing a dummy fourth column allows the
weighted COA of R to proceed. So the problem appears to be related to
column number in R. Why?

We have got round the problem by weighting the R table in Excel and
proceeding with an unweighted COA. Is this valid?

The attached file contains more information on the data matrices.

Thank you for your help in advance.
