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!

special characters
...> d=read.csv2(filename)

The special characters are accepted inside strings, but not as names of
variables.
Could you tell me what to set in R to make it accept these special
characters as names?
Thank you,

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

filling the area
Please, how to fill the area under the curve?
x <- c(1:10)
y <- c(rnorm(10))
plot(x,y)
lines(x,y)
Thanks,
