I am using the R function SpatialFiltering to my land value dataset.

Dear R Users,
I would like to use R to fit a Weighted Least Square model for a
binary response variable, say Y. The model is actually the model
widely used for a binary dependent variable when the logistic model
has not been invented. The weight is 1/(E(Y)(1-E(Y)).
Could someone help me out?
Thank you, Joshua!
I got what I was looking for using this command:
as.numeric(grepl(\\*$, qb$Player))
Where the variable name is Player in dataset qb.

Saptarshi,
if you look at the sheer number of shared libraries involved, heap

Finding the reason for such problems is usually difficult, but almost

Well, when a think of it using an array would be a simple solution.

Yes you use the linear predictor from your regression as the dependent

You can depict the ols model with nomogram(). Note that there are so many

I'm trying to figure out common approach on calculating MA on a dataset

After digging around, I believe functions rollmean and rollaply should
be used.
However I don't quite understand the requirements for the underlying data.
Should it be zoo object type?
