[GRASS-user] Using RStudio in a GRASS GIS session

Sun Apr 21 11:40:00 PDT 2024

Thanks Roger,

Thanks a lot.

I tried to use R within a GRASS session following the instructions. Hmm the
problem seems to be the rtools42 (rtools not being detected), however the
path is correct.

Kind regards

Sibylle

Enter:

library(rgrass)

at the R prompt in rstudio, not at the GRASS console prompt; it is an R
command.

The error message:

Der Befehl "library" ist entweder falsch geschrieben oder konnte nicht
gefunden werden.

comes from Windows, not GRASS or R.

Dear Roger

Dear community

May aim is to use RStudio in a GRASS GIS session, to visualize raster and
vector data: e.g. a boxplot of a species raster file or boxplot of a species
raster file differentiated for different regions (vector file). 

Similar in 

https://ecodiv.earth/post/drawing-boxplots-of-raster-values/

Because of my name with “ö” I changed the location to C:/GrassGIS: this
seems to be the solution for the error when staring GRASS. No warming
anymore.

Using the command line, I was able to produce a boxplot.

I am more comfortable in R, so I tried starting R inside the GRASS console
(as suggested for windows) following the code here:

https://rsbivand.github.io/rgrass/articles/use.html

However, I am still struggling around with the error

The command "library" is either misspelled or
could not be found.

library(rgrass)

Der Befehl "library" ist entweder falsch geschrieben oder

konnte nicht gefunden werden.

(Sat Apr 20 12:57:24 2024) Command ended with non-zero return code 1 (0 sec)

Kind regards

Sibylle

First tell us exactly what you do. Do you start GRASS first (how was GRASS
installed, which version?), then what? The first message suggests a failed
GRASS installation. Can you use GRASS at all? Try to run any regular example
on the data in your location in GRASS to check that GRASS works before
anything else.

Dear community
Dear Roger

I suppose it is my name
Here the output from the console:

C:\Users\Sibylle Stöckli>

Do you have a GRASS location and wish to use R on the data in that location?
Then start GRASS first and start rstudio from inside GRASS.

The error messages suggest that something is missing in your installation.
