: spatial autocorrelation on a sphere
Dan Bebber dbebber@... writes:
I would like to write a spatial correlation structure function for
nlme, that replicates the ability of such functions in the 'ramps'
package to calculate great circle distances, e.g. corRSpher(form = ~
lat + lon, metric
imagine it must be possible for nlme.

Please be assured, I really did
I have spatial data on a sphere (the Earth) for which I would like to run an
gls model assuming that the errors are autcorrelated, i.e. including a
corSpatial correlation in the model specification.
In this case the distance metric should be calculated on the sphere, therefore
metric =
0.

Many thanks,

I don't know my way around SpatialPolygonsDataFrame objects very well, and have
no idea how to fix the errant hole.
Any help greatly appreciated.

the plotting symbols in metafiles appear as vectors?
