   Hi

   I'm using the gss package to fit thin plate splines. I've fitted the tps
   without problems and got a ssanova object. Then I wanted to do some
   prediction using a new set of data (latlon data) and I got an error
   message:

   > predict.ssanova(recs.spliney,recn.grid,se.fit=FALSE)
   Error in array(x, c(length(x), 1), if (!is.null(names(x)))
   list(names(x),  :
	   attempt to set an attribute on NULL

   Can someone help me with this ?

   Thanks

   EJ

Is recn.grid a data frame with the same variable names as used in the
fitting formula?
