Dear users,
I'm getting the following error when trying to compile my BUGS code:

Dear all:
I am working on analyzing the spatial structure of tree and environment data
as a preliminary step before doing further analysis. I was wondering which R
functions you recommend to assess the degree of spatial structure for tree

Dear Edzer,
my.STSDF - as(my.STFDF, STSDF) does exactly what it should. I have a
STSDF object with several columns of data that have NAs for one variable but
not for other variables. I wanted to keep only those observations in space
and time that had data (no NAs) for all variables (see
Hi,
I have a question about stplot.
Let's say I'd like to plot via multi-panel a series of plots separated by a
given time interval. How can I accomplish that?
Also, let's say this time interval is specified between thow given time
instances, for example: every week between 14/07/11 and

Hi,
I am having difficulty in reading data for further use that is in
ASCII grid format (it's the UN population data from
http://sedac.ciesin.columbia.edu/gpw). I used readGDAL function which
leaves me with SpatialGridDataFrame class object, but apart from
creating simple image with

Hello,
I use the raster package for asci files
it works great and has a very hands on access to get statistics or do

As you said, readGDAL will give you a SpatialGridDataFrame object, which
behaves much like a normal data.framet. Your best bet is to run it through
names to see what data are available to work with:
names(map)
Like a regular data.frame this will give you the bands or data read in from
your
Dear Users,
I am fitting a spatial model a multilevel data (mouth-tooth-surface) of very
small prevalence. Therefore in my case every person will act as a map. I am
looking at a binary outcome of a tooth surface which is nested in the tooth and
nested in the mouth. So I have a
If you want to see more info of the dataset, you can also view it with

Learning about existence of band1 was what I actually needed. Apart
from one bigger spatial econometrics project, I haven't done much work
with R yet, so I still lack some knowledge on basic operations - I
will try to remember about the names() function next time. I thought
the problem would lie
Hi Reza,
I wrote a simple function that creates choropleths in R. You can check out
the code on my github repos and some documentation on this post.

No worries. good luck!

The FID values are stored as ogr:layername fid=F0 (and F1,

Dear R-users,
I'd like to use a corStruct matrix in fitting a binomial model, but I
need to define it using a pre-calculated distance matrix (instead of
feeding it with spatial coordinates). Do you have any idea on how to do
this in a simple manner?
So far the only way I could imagine was to
