Hi,
Did you try to export the data using writeGDAL (rgdal-package)? Does
this generate the same problem?
cheers,
Paul

Does anybody know how to convert points to the SHP polygons?
OR whether we can generate some SHP polygons randomly in R?
##Example##
win-owin(c(0,1),c(0,1))
pp - runifpoint(10) #generate 10 points
#i want to change these 10 points into 10 SHP polygons,something

Hello everybody,
I am using 'spsample' to derive points along a line and it works perfectly
by doing the following :

sppts - spsample(xx, n=50, type=random)

Dear Pete, Edzer,
If this is of any help, few years ago we have played with using auxiliary maps
to interpolate
categorical variables (multi-indicators?). The results are reported in:
Hengl T., Toomanian N., Reuter H.I., Malakouti M.J. 2007. Methods to

Karen,
The approach I have taken to this problem in the past, is to fit a
Poisson - Normal model and use the normal variation in the Poisson
means to capture spatial dependence. Essentially, conditional on the
random effects and predictors, the outcome is assumed to be an
independently drawn

I am trying to spatially interpolate snow height data of about 100
stations in a mountain range. In addition, I have a large DEM (SRTM,
90 meters resolution, 2.5 million cells) which also serves as an
interpolation raster (just like meuse.grid). As the snow

The vectorField function is exactly what I needed. Thanks to everyone else
for quick responses.

I can see that this section of the book is indeed very dense;
introductions to collocated cokriging are (IIRC) Pierre Goovaerts book
and perhaps GSLIB literature.
