[GRASS-user] i.spec.sam error

[Jaya Krishnan]

HI again Markus,

Sorry to bother you again. But I was thinking of using Spectral Angle
Mapper in RStudio's RSToolbox package as an alternative. So I followed the
steps at the link
https://grasswiki.osgeo.org/wiki/R_statistics/rgrass7#Using_RStudio_in_a_GRASS_GIS_session
but am unable to run RStudio at the GRASS command prompt. The error is
again * 'rstudio' is not recognized as an internal or external
command,operable program or batch file *(attaching error below).
I changed the path in env.bat file in the GRASS folder to include RStudio
and R, but no luck.

Might there be a solution?

Thanks,

Jaya
