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?
