[GRASS-user] Fwd: Using g.extension in with rgrass7 in R

[James Duffy]

Solved.

I found that closing RStudio and then installing GRASS extensions, and
reopening RStudio afterwards solved the issue. Solution described here

Hello,

I'm trying to use GRASS in RStudio using the 'rgrass7' pacakge.

So far I have:











*library(rgrass7)initGRASS(gisBase =
"C:/OSGeo4W64/apps/grass/grass-7.3.svn",          gisDbase =
"C:/Sandbox/RGRASS/",          location = "TEST", mapset =
"MAP1",override=TRUE)in.rast <-
"C:/Users/James/Desktop/15m_site2/subset_output/15m_site2_subset_ortho.tif"execGRASS("r.in.gdal",
flags="o", parameters=list(input=in.rast, output="ortho"))*
Which works fine!

However, when I want to install an extension with:



*execGRASS("g.extension", parameters=list(extension="i.segment.uspo",
operation="add")) *
I get the following error:



















*Downloading precompiled GRASS Addons <i.segment.uspo>...ERROR: Variable

Can anyone tell me where I have to set the 'LOCATION_NAME' please?

Kind regards

James
