General questions

What does FUTURES stand for:

FUTure Urban-Regional Environment Simulation

Running FUTURES

Windows-specific

Running r.futures.potential gives ``WindowsError: The system cannot find the file specified`

Module r.futures.potential is calling Rscript binary and it can't find it. Try to reinstall GRASS, during installation it looks for it. Alternatively look where R is installed and add the path to the binary to your PATH variable.

Running r.futures.potential gives IOError: Permission denied: "potential.csv"

You are attempting to write output potential.csv file where you don't have permission, such as in C:, change working directory (in GUI menu in Settings) or change directory in terminal to where you can create files.

During running r.futures.potential it can't find required R packages, although I have them installed.

Try to install them again from within GRASS terminal: launch R interactively and install the packages.

MacOS-specific

Running r.futures.potential gives ``OSError: [Errno 2] No such file or directory`

Module r.futures.potential is calling Rscript binary and it can't find it. Providing you have R installed, open a new terminal and run:

which R

In the GRASS terminal now append this path to PATH variable:

export PATH="$PATH:/usr/local/bin/"

Reopen GUI with g.gui, or run r.futures.potential from terminal.
