Hi Bernardo,
The presented system() command requires grass to be in the system's
PATH. An alternative is to use the R package link2GI
<https://r-spatial.github.io/link2GI/> to get the gisBase argument of
initGRASS(); AFAIK it has been updated to also support GRASS 8.
Possible approach copied from an R markdown document:
gisbase_grass <-
if (interactive()) {
if (.Platform$OS.type == "windows")
link2GI::paramGRASSw()$gisbase_GRASS[1] else {
link2GI::paramGRASSx()$gisbase_GRASS[1]
}
} else params$gisbase_grass
Regards
Floris

*Emne:* [GRASS-stats] 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:

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
<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Frdrr.io%2Fr%2Fbase%2Fsystem.html&data=05%7C01%7Croger.bivand%40nhh.no%7C9ee806160e144928a19908da8751a4d1%7C33a15b2f849941998d56f20b5aa91af2%7C0%7C0%7C637971081981258278%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=PWx9f7SSQY6EQn2nPNsCFAdIjT3hp3T6Kk7S9%2BAKnDs%3D&reserved=0>("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
