Thanks to Tony Plate (and his simple example - message to self: "follow
the posting guide's advice next time!!!"), I realised that deparse
(substitute( )) was taking place *after* I had modified x and y in
situations where some columns contained all zero values. Moving the
offending lines above the modifying if() statements solves the problem.
So - not a problem with method dispatch at all, except perhaps within my
brain just now...
All the best,
Gav
