Hi Marc,
those packages are just interfaces to the netcdf library that must
already exist on your machine. Try installing the netcdf library
first, and then installing the R package.
You will need the development version of the netcdf library
installed in order to compile the R packages. Hopefully the exact
package name will be obvious in the package manager on your system.
Thanks a lot for these infos.
Here are the last news for my problem of installation package in 3.1:
I have installed macport and then I have tried to install
development version of netcdf library:
sudo port install netcdf-devel
Error: Port netcdf-devel not found
Macports installs its packages in folders that are not standard and
then R packages don't find them (at least that's my understanding of
the reason Macports causes troubles with R packages.) You are asked
not to use it for packages that R will be linking to. So maybe that
error will be a boon rather than a bane. Doing a search on: [ macports
Urbanek] in the archive of r-sig-mac should provide further details.
This really should have been posted there.
The netcdf library is available in macport but not the development
one.
In the meantime, I have tried to install ncdf and ncdf4 package
after downloading the MacosX binary versions at:
http://cran.r-project.org/bin/macosx/contrib/r-release/ncdf_1.6.6.tgz
http://cran.r-project.org/bin/macosx/contrib/r-release/ncdf4_1.10.tgz
I have installed both using the install_local() function of the
package devtools.
Both install and run correctly.
The same procedure applied to RNetCDF (http://cran.r-project.org/web/packages/RNetCDF/index.html
) has produced an error during installation.
I have installed other packages in 3.1, or directly using
install.packages() or loading the MacosX binary and using
install_local(). I have still a problem with rgdal (http://cran.r-project.org/web/packages/rgdal/index.html
). Probably again it is a problem of library (gdal) that is not
present. I will wait that binary library is available in CRAN.
GDAL is an external package.
http://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries
rgdal is the R interface package that you would use to get GDAL
functionality.
