Hi All,
Following Edzer's examples, I have tried to test the effects of the
specification of alpha in variogram on the results of fit.variogram as below:

> v0 = variogram(zinc~1,meuse, alpha = 0, tol.hor = 45)

Hi Barry,
I'll be happy to join :)
I'm sure there's some more spatial useRs out there in Warwick at the moment,
Cheers,

Hi Robert,
thanks for the full report. The suggestion to write a raster file with a
certain NA values was all I needed. Thinking about it now, other users
would probably also like to be able to determine the NA-value when
writing files, so I wouldn't expect a common need.
I will try to stick to
Hi everybody,
I have a SpatialLines object that I created by using the gBoundary()
function on a SpatialPolygons object. I've attached a plot ("SpatialLines
Segmentation.png") of the SpatialLines object to this email. What I would
like to do, is segment these SpatialLines wherever there is an in
Brian,
If you simply want to change the NA flag (i.e. the value used used in a
_file_ to represent NA), you should use the NAvalue function
NAvalue(rast) <- -9995
But note that this is only to be used when there is an error in the file
metadata, or other reason why values that should be NA are n

Hello,
As a learning experience I have made a kriger in R and have been exploring
different variogram models. I really like the speed and simplicity of
entering data to the gstat package which solves much faster than my toy
kriger. I have taken a brief look at the gstat C source code where the
