Dear GeoR-er,
If I use the variog function in the latest release of geoR, the first lag is
always ignored.
For instance, if you read in geodata, calculates the variogram using the
variog function and give in a uvec like uvec=seq(0,max,by=2.44), it only
starts giving results from distance=4.88 and

As I read it, both difficulties arise on the DCOM side,
not in the R syntax. Problem 1, and I'm just guessing,

lines.

Dear Anupam,
I may be wrong, but I don't think that there's any standard method to use
in plotting with case weights. I can think of two approaches, however: (1)
If you have a large sample, and if the range of the weights isn't too
large, you could sample your observations with probability of

Depending on your version of Word that simply is *not* true!

Your problem may also be that you can't get the figure to print from Word?
To get Word to print anything other than a blank box for the eps, you will

Do you mean the pls.pcr package by Prof. Wehrens? This is what I do:
o Code the two groups as 0s and 1s (numeric, not factor).
o Run PLS as usual. Cases with predicted values 0.5 get
classified as 1s, otherwise as 0s.
o Note that you need to modify the code inside the mvr()

Great and thanks a lot! Yes, it is the package from Prof. Wehrens. So I
just run the PLS like a Logistic Regression, coding the endogenous

So no need of specifying a binary-link function (as we have to when
using glm)?
And yes of course: I need the LVs which give the

If you coerce design into a data frame and then do

that should work.
