...or example), and similarly at the right-hand end. This seems simpler and more elegant than brute force QR on the full matrix of derivatives. But I may have missed some reason why it can't be used.

After a one-way anova, se.contrast computes the standard error of a contrast, but not the value of the contrast itself. Wouldn't this be useful?

Hi, You should look at Pinheiro and Bates (2000) Mixed-effects models in S and S-Plus. It describes how to format the correlation matrix to pass to functions lme and gls. Basically, the correlation matrix has to be one of the corStruct classes, probably corSymm for your example. So in the call to lme (or gls if you really have no random effects), use something like:

...spline interpolant has value 1.2266-(-1.3493)=2.5759 at x=1, not 2.5366.
