Hello all!
I am trying to estimate four parameters (mu, sigma, theta and lambda) of a model
Using the nls package in R, I can only get it to work if I limit the number of
parameters to be estimated to three (i.e. mu, sigma and theta) as in the first
model - mod1 - below. Including a fourth param
Hi,
I'm sorry I cant post a reproducible example, but the data sets involve are
too large. I'm currently trying to create a mosaic from 2 different Landsat

the mosaic command, I'm doing

Hi Gavan,
After running the code in your message, do something like this...
xp <- c(.2,.3) ## x values for prediction
Xp <- PredictMat(sm,data.frame(x=xp))[,-3] ## prediction matrix
yp <- predict(b,list(X=Xp,off=rep(.6,2))) ## call predict.gam
points(xp,yp,col=2) ## plot points
... hope that's
Hi Ivo
If you want to add lines, text etc you can do that by a lattice panel
function included in it would be panel.contour
something like (untested)
contourplot(...
panel = function(x,y, etc,...){
panel.countorplot(x,y
Hi Ivo,
Not in a sane way. Have a look at the latticeExtra package that allows
most of these things to be done.

There are lattice equivalents to many of the base prim
Exactly what I thought too the first time I read ?merge. R sometimes has its

Sorry, my first response was too hasty. Per the help file you need to use some
kind of interpolation method to resample whatever random data points you have
in a regular grid before you give it to contourplot.

You do not appear to understand what merge() does. Go through the worked
examples in ?merge so that you do.
FWIW, I would agree that the Help file is cryptic and difficult to
understand. Perhaps going through a tutorial on database "join" operations
might help.

Not sure what the issue is here. If I click on the link I provided, I go

Try this
plot(1:33292, 1:33292,col=Color(33292))
and then decide again whether or not it is working.

Your example is not reproducible. You pass 33292 colors to plot, but never

thank you. yes, I got bitten by "FAQ 7.22: Why do lattice/trellis
graphics not work?" It had never occurred to me that this could be
expected behavior or a FAQ. (didn't show up in a google search for
contourplot.) Unless one knows, this is a puzzler. Thanks for the
pointer. so, a minimum work
The help for for contourplot answers this question in the description of the
