I think the issue is, most GDAL installations don't have the Geopackage raster
driver [1] installed by default, which lists "Needs libsqlite3 (and any or all
of PNG, JPEG, WEBP drivers)" for it to be available. At least on my Homebrew
installation of GDAL, this driver wasn't built out of the
Hello Roman,
A couple of suggested options: You can try and use the arcgisbinding package
[1] to pull the data directly into R via ArcGIS, as you mentioned you have
ArcGIS available [presumably on Windows or in a VM]. It will access the data
directly, and let you create sp and sf objects out
This Thursday, August 31st, Esri is hosting an online workshop
detailing how ArcGIS can be used in conjunction with R, using
the arcgisbinding package:
https://www.esri.com/training/catalog/596e5ab6b826875993ba4fd9/
There are three time slots available, the bottom of the linked page
includes
Try passing the configure arguments to the command directly to rproj:
install.packages('rgdal', configure.args =
'--with-proj-include=/correct/proj4/include --with-proj-lib=/correct/proj4/lib
--with-proj-share=/correct/proj4/share')

Glen,
Round-tripping projection information can be tricky, in part because the
normalization routines vary between different stacks, and what counts
as the same form is also implementation dependent. In this case
(round-tripping with ArcGIS), you may be better off using the
arcgisbinding package
I've had good luck using checkinstall [1] to manage custom compiled packages as
well, if you do want to have custom compiled packages which are registered with
the system package management system. I've found this to be invaluable when
working with dependency heavy packages like GDAL.

You can extract the data fairly easily using the REST API to pull out
what you want. For example, this URL contains the regions:
http://www.arcgis.com/home/item.html?id=0dd32a9c77b8400ebf60261571b9134b
That data can be downloaded directly in the browser, or using something
like cURL. Note that
You could also look at calling out to a GIS environment from R to make the
calculation. For example, there are bridge libraries to talk to SAGA [1], GRASS
[2], and ArcGIS [3] from within R which can all read data formats raster can
create.

Try installing it from CRAN instead:
# R version 3.1.3 (2015-03-09) -- "Smooth Sidewalk"
# Platform: i386-w64-mingw32/i386 (32-bit)
install.packages("SDMTools")
# le package ‘SDMTools’ a été décompressé et les sommes MD5 ont été
vérifiées avec succés

I missed a step -- first you'll need to add Homebrew-versions [1], which
provides older releases of existing packages:
brew tap homebrew/versions
The commands listed should then work.

Have you tried with the homebrew project? HDF4 isn¹t a default supported
driver, but it¹s easy enough to add:
brew install hdf4
# prefer hdf4 links over NetCDF
brew link --overwrite hdf4
brew install gdal --complete --enable-unsupported --with-hdf4
# check what drivers are installed,
The specific projection information is contained within the raster
datasets you download, in the related ASCII, Bil or GRID file. The
metadata you see on that page is just a human readable representation of
the data coverage, not intended to directly map to the full spatial
reference.

Dr. Dave,
This list is for issues regarding spatial R. You¹ll have better luck using
the support systems for the Kepler project:
