Look at Rcmdr as the base for your additional menu functions.
I am using it for my introductory courses and have added my own menu items.
From CRAN, download and install Rcmdr and read it's documentation.
Also from CRAN you can download and install my addin library RcmdrPlugin.HH
The latter will
There are dozens of functions within R and contributed packages that do
this. The spatial statistics packages (see the spatial task view on CRAN)
is certainly where most are concentrated, but thin plate splines (in splines
packages, I believe), tensor product splines (in mgcv package), local

Killing one of those loops is quite simple. The other may be
harder.

Dear all,
I want to min integrate( (p1*dnorm+p2*dnorm+p3*dnorm)^(1.3)) for p, mu,
and sigma.
So, I have to estimate 8 parameters(p3=1-p1-p2).
Sometimes I got some results, but it was bad, sometimes, I got this

First time using, the mailing list and I'm somewhat new to R, so excuse me if I
do anything wrong.
I was wondering how I would set up a two way ANOVA for the following data:

You don't, because the operation is not well defined.
Using anova( ) on a single linear model object will fit a sequential
sequence of sub-models got by adding the terms into the linear model, as
they appear in the model formula, one by one.
In non-linear regression there is no unique definition
The package 'VGAM' (all caps) has a betabinomial model fitting facility
in it.
(I doubt this will save your soul, by the way, but it may save your
butt. I think that is probably your most immediate concern, though.)

Hi,
your post is hardly readable because it is so spread out over several pages.
Can you repost it?
Besides that I do not understand your question fully. The y is your
dependent variable and as it looks the A*B would be Sulfur*Nitrogen if these
are your variable names.
You can also take a look
Dear Bert,
Thanks for your reply - I indeed saw a lot of functions using:
help.search(smooth)
The problem is that most seem to not be very appropriate to what I'd like, or
they seem extremely complicated (e.g. gma). I am probably missing
something as I don't

Ben,
I would like to test the sulfur on the clover field, nitrogen on the clover
field and then test for the presence of interaction.
Sorry about the last email, seems it really screwed itself over, here it is
again, hopefully nicer:

Hello
I have a number of different data sets, each loaded as a matrix. I'd
like to plot them in a way that the data in the first column of each
matrix is plotted on the same pair of axes.
What I'm doing now is to call plot() for the data on the first matrix,
then call points() for the other
