numerical differentiation in R? (for optim "SANN" parscale)
...way, I couln't find it neither in the help, nor in the non-internal, displayable source of optim. Could anyone tell me where to find such a function? And if it really is what I need for `parscale'? Thank you!

for plots
...ed on my screen. How can I get a plot before the last plot? I mean if the object has several plots how can I get those? "gam.object <- gam(y ~ s(x,6) + z,data=gam.data) plot(gam.object,se=TRUE)" Thank you. Brad.

Hypothesis testing after optim
Hi folks: Does anyone know of a way to do (linear) hypothesis tests of parameters after fitting a maximum-likelihood model w/ optim? I can't seem to find anything like a Wald test whose documentation says it applies to optim output. Also, thanks again to everyone who gave me feedback on the robustness of ML estimation in R!

gamm with correlation structure question
Dear group, I am trying to use gamm() in mgcv. Here's the scenario. The data frame has approx. 110K observations with information on paediatric readmission binary outcome (Y/N) and total volume of their most responsible physician as the covariate. Since any physician can have multiple patients, the data contains clustering structure which I am trying to account for. My original formula is a <- gamm(readmission~s(volume,fx=F), corre...
