Dear Community,
trying to get through the examples from Applied Spatial Data Analysis with R
I got problems with the gpclib package.
The library was loaded correctly:
library(gpclib)
General Polygon Clipper Library for R (version 1.5-1)
Type 'class ? gpc.poly' for help
... but then
Just issue the command once in the session.
gpclibPermit()
Alternatively, you could wait for the rgeos package.

Dear Community,
Dear all,
I have a problem converting a large binary sparse weight matrix (62025 *

Is there a function that creates a listw object from a sparse matrix?
Thank you in advance.
Best regards

You mean in package Matrix, and as described in ?TsparseMatrix-class?

Dear all,
this is probably a very stupid question -- in case it is I apologize in
advance.
I'm not very familiar with spatial statistics, although I have used the
spdep package previously (specifically the moran.mc and moran.test
functions) in a
