Hi Benjamin,

Grass70, grass 64, R gdal, proj - everything via homebrew.
See https://github.com/OSGeo/homebrew-osgeo4mac tap for the formulas -
very useful tap!

The code I used in R is as follow:
--8<---------------cut here---------------start------------->8---
switch(
Sys.info()[['sysname']],
Windows = { print("I'm a Windows PC.") },
Linux = { print("I'm a Penguin.") },
Darwin = { print("I'm a Mac.");
Sys.setenv( DYLD_LIBRARY_PATH = paste(
"/Applications/GRASS-7.0.app/Contents/MacOS/lib",
"/Users/rainerkrug/Library/GRASS/7.0/Modules/lib",
"/Library/GRASS/7.0/Modules/lib",
"/Applications/GRASS-7.0.app/Contents/MacOS/lib/FFTW3.framework/Versions/3",
":DYLD_LIBRARY_PATH",
sep = ":"
)
)
}
)
--8<---------------cut here---------------end--------------->8---
This should be done before you start using grass from R.
Please be aware that you might have to change some paths.
Also, if you start R in grass, you don't need this as it is done by
GRASS GIS. It also depends which commands you are using in GRASS -
different some commands require additional paths.
The reason is that the frameworks are kind of isolated containers which
contain everything, including libraries. To avoid conflicts between
different installation (Frameworks or .app folders - they are in these
respect similar), they are not in the universal paths - which is also
the reason that they are not available easily as in Linux from the
terminal. SO programs have to set the paths so that they can find the
libraries in the frameworks.
Homebrew kind of avoids this and has a linux approach with all libraries
which are installed via homebrew are available globally as they are in
the path.
So as I see it, homebrew provides a more consistent environment for the
kind of work one is doing with R and grass.
Hope this helps,
Rainer
