Re: [R-sig-Geo] convert "errorsarlm" to "lm"
Regarding your question about MRF, I don't know what it is...
I know that the package piecewiseSEM accept the following object types:
‘lm‘, ‘rq‘, ‘glm‘, ‘glm.nb‘, ‘gls‘, ‘pgls‘, ‘merMod‘, ‘merModLmerTest‘,
‘lme‘, ‘glmmPQL‘, ‘glmmadmb‘, and ‘glmmTMB‘.
so "transformation" of errorsarlm to any of these object should solve the
problem.
Below there is a code where a dataset is simulated and analyzed using 'lm'
and 'errorsarlm'. Only 'lm' is accepted for
SEM analysis.
Thanks,
Niv

Just like Mike I too will rely on raster for many years still and I will be very happy to support efforts on this or whatever else the community leaders (Edzer, Roger, and others) decide is the best way for us to move forward.

Re: [R-sig-Geo] Is the raster package still receiving updates?
The the NOTEs on CRAN and the issues raised on Mike's raster-rforge GH repo to me suggest that raster has, for a while now, reached a mature state. Of course, you'd wish that raster development, in terms of extending its power and features, would continue the pace it did 10 years ago, but that's a different issue. Mike has write access to the raster r-forge sources, it shouldn't be hard to support Robert with current issues. Right after rstudio::conf (Feb 4/5) I'm meeting with Robert Hijmans and Etienne Racine, to discuss, and work on raster future and integration of rasters and stars. Anyone interested, feel free to join. Stars has the ambition to jump over raster, in the sense that it doesn't want to have the local hard drive as a limitation. That calls for rethinking quite a few things. So far, things are still all in main memory but it already integrates with sf: https://gist.github.com/edzer/381dac079ddcd5174be31209675b3822 and handles time stacks of different attributes in single objects.

Re: [R-sig-Geo] spplot help, please
The others are right, there is no state map in your code that you might
add to the points plot.
After a quick inspection of which geographic area we are dealing with,
here is one possible - and quite basic - solution on how to add state
polygons of the US (if that is what you intend to do) to your plot:
## download state polygons for the us
library(raster)
usa = getData("GADM", country = "USA", level = 1)
## create subset of state polygons (otherwise spplot() will take quite
long)
proj4string(res.adpt$SDF) = "+init=epsg:4326"
ext = extend(extent(res.adpt$SDF), 2.5)
states = crop(usa, ext)
## add state boundaries using 'sp.layout'
p = spplot(res.adpt$SDF, c("ols.e","gwr.e"), main = "Residuals",
sp.layout = list("sp.polygons", states))
p
Alternatively, you could also use latticeExtra::layer() instead of
'sp.layout'. Simply have a look at the help pages for further details.
Cheers,
Florian

Re: [R-sig-Geo] Is the raster package still receiving updates?
Yes, this sounds fruitful. For now, I suggest that those wishing to enhance raster do so in an additional package enhancing raster and depending on it. Immediately, we should help Robert resolve the notes in the tests, they do not affect functionality now, but deserve attention to bring the package into full CRAN compliance. I can help with this.

Re: [R-sig-Geo] Is the raster package still receiving updates?
Many of us rely on the raster package as a crucial basis for their work. Big thank to Robert. Nevertheless to contribute needs to focus needs and ressources. Maybe an information exchange/discussion with Robert about options such as if/how the interested community can support would be more productive. cheers Chris Am 21.10.2017 um 06:52 schrieb Roger Bivand: The CRAN raster package has not been abandoned, if it had, it would have been reclassified as orphaned. Its test results have notes but no warnings or errors. It would be orphaned if the maintainer did not respond to CRAN requests to resolve test errors. Consequently, you are suggesting a fork, and should rename any package. Only the maintainer may update existing CRAN packages. I would not think that forking an existing CRAN package is the most productive way of contributing to the community. The package has many reverse dependencies, so setting up a test framework to find backwards incompatibilities would be crucial. Of course, all contributions are welcome.

I'm keen, but haven't done the work needed to flesh this out properly: https://github.com/mdsumner/raster-rforge/issues I have not checked if there's been any commits to r-forge since I cloned this.
