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

Fri Apr 19 06:09:01 PDT 2024

Dear community

Thank you very much for all your input.

Unfortunately I got always the same error

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

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

Find here some info about the operating system:

GRASS version: 8.3.2

Hi Sybille,

I have never tried opening Rstudio from the GRASS terminal, but I know that it is possible to open R. So as others have mentioned, you could try to first open R (from the GRASS terminal) and within it try `library(rgrass)` (or `install.packages("rgrass")` if it was not installed yet).

But I also know there are some issues when working with both R/RStudio and GRASS in Windows, also related to how GRASS was installed and if R/Rstudio are recognized in the PATH variables. Please take a look at these notes here and check if any of that helps you: Connecting to GRASS from R in Windows · Issue #10 · NINAnor/oneimpact (github.com) <https://github.com/NINAnor/oneimpact/issues/10> 

Best

Bernardo

>From the message that library is not found, I wonder, did you type 

GRASS> rstudio & library(grass) 

all on the command line? 

Just to be sure, you should ope Grass gis. And in the grass gis command line, type

rstudio &

Next, after RStudio opens,  you type the following in RStudio

library(grass)

Hello Sibylle,

Perhaps you can tell us some details about your operative system, which GRASS installer you are using (i.e., standalone or OSGeo4W), how did you start GRASS, if R and RStudio are installed. 

>From your email, I do not understand why GRASS is not recognized as a command, as it seems you **are** already within a GRASS session on the terminal? (i.e. you have a GRASS prompt there `GRASS>`).

Silly question, do you have the 'rgrass' library installed?

i.e. can you do `library(rgrass)` at the R command prompt (without rstudio)?

Dear community

To use RStudio in a GRASS GIS session I used the command line
GRASS> rstudio &
library(rgrass)
(see https://grasswiki.osgeo.org/wiki/R_statistics/rgrass)

Unfortunately I was not able to solve the error message:
- The command "GRASS" is either misspelled or
could not be found.
- The command "library" is either misspelled or
could not be found.

Kind regards
Sibylle
