Michael,
I did not try it, but I think the below accomplishes the same. If at
all possible, you should avoid using ascii format files (that leads to
slow processing).

Right for cross-section models, but the question was about spatial panel
models. In that case. it may be
Hello,
Yes, to add something to what prof Bivand wrote. to manually create the WX
remember to use the Kronecker product of the time Identity and the Weight
matrix. and it should be straight forward.

Hi everyone:
I would like to plot the observations of housing prices included in the Lucas
County data of spdep package. The problem is that I want to plot these
observations in a map of Lucas County. I have found a map of Lucas County in an

after searching and searching I couldn´t find a way to that.
instead, I simply came back in the loops and inserted my data.frame in the

Hi all,
Ok so I have a spatial data set with over 3000 polygons. I used poly2nb() to
identify neighbour relationships and make an nb object. Of the polygons, about
30 or 40 are islands and have no neighbours according to polynb. Prior to doing
Bayesian smoothing, I wish to assign neighbours to

Dear All,
Please which of these packages - gstat and geoR is better for fitting
spatial covariance structure model for spatial data with 20,000
observations. Kindly recommend any other package you think can fit such
model.
Thank you.

Dear All,
I have three datasets and would like co know how much N was used in my
calculations.
I read the data into a multi-dimensional array with dimensions (nx, ny,
ntsteps, ndatasets), e.g. with a smaller example dataset:
# nx ny nsteps ndatasets
dat =

Juan and Roger, thanks for the replies.
If I construct the spatially lagged independent variables for each year period,
add them to the panel dataset, and then use ML estimation from splm package,
will it work?

You can look into using the spBayes package using gaussian predictive process
models to handle the large number of observations.
