Hi Māris, Thank you for your help and suggestions… but, how, within the GUI do I set GISDBASE… I have looked but cannot find how to do this… Regards, Tom On Tue, Aug 30, 2022 at 1:33 AM Maris Nartiss wrote: > otrd., 2022. g. 30. aug., plkst. 07:10 — lietotājs Wolf Bergenheim > () rakstīja: > > > > Hi Tom, > > > > 1) To point GRASS to the GISDBASE on the external drive, simply start > GRASS once with > > > > grass /external_ntfs_mount/some_location/mapset > > > > Meaning that you give as argument the path to a mapset that you want to > use in the GISDBASE on the external btfs drive.

Re: [GRASS-user] Running r-grass examples when building a R package
Hi Stefan,(and thanks Roger and Floris for replying as well)
Your solution worked perfectly, Stefan. Thanks a lot!In the case of continuous
integration within Github as it is the case, it seems we must ask GRASS to be
installed in the virtual machine.
This could be done with Stefan's suggestion, adding these lines to the yaml
file within .github/workflows:
- name: Install GRASS GIS and other dependencies run: | sudo
apt-get update -qq sudo apt-get install -y -qq grass grass-dev
grass-doc wget
You can also see it here: Install GRASS for CI by ninsbl · Pull Request #11 ·
NINAnor/oneimpact (github.com)
I guess this could be documented for GRASS/R users somewhere? Maybe in some
wiki?Any suggestion on where to add this?

Hi Bernardo,
Seems like GRASS GIS isn`t installed on the CI VM.
Please see:
https://github.com/NINAnor/oneimpact/pulls
You may add UbuntuGIS PPAs if you want other versions than shipped by plain
Ubuntu.
Cheers
Stefan

Subject: [GRASS-user] Running r-grass examples when building a R package
Dear all,
I am building a R package and some of the functions use rgrass to connect to a
GRASS project and run thingfs within GRASS.
I have now set up a webpage for the package using pkgdown in integrated to
Github actions. This means when I push new commits all the examples of R
functions are run again and the webpage is updated with the results of the
examples. Here is the webpage: https://ninanor.github.io/oneimpact/
All works fine, except the functions calling GRASS. When I run the examples
form my local computer everything works, but in the Github actions it does not
run, apparently because the command
system("grass78 --config path", intern = T)
to find the GRASS folder and use within rgrass::initGRASS does not work, so the
connection between R and GRASS do not exist.
Does someone in the group has experience with that and could help with hints to
solve it?
Is there a recommended way to make sure Github actions know where GRASS is and
use it?
Best
Bernardo
