Hello everyone, In this video I will share an introduction on how to use GRASS GIS in your R studio system.
By combining R studio and GRASS GIS you can easily do the statistical analysis by R and also execute the GRASS command for spatial data analysis.
First my PC is Mac OS sierra… which is a bit more complicated when you try to install GRASS GIS for MAC. I will guide some of the important issue here:
Download Grass GIS for Mac - A free and open source Geographic Information System application specially designed for geospatial data management and analysis. Download GRASS for free. GRASS is a free and open source Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling, and visualization.
How to install
Download GRASS GIS for free. GRASS GIS - Geographic Resources Analysis Support System, commonly referred to as GRASS GIS, is a Geographic Information System (GIS) used for data management, image processing, graphics production, spatial modelling, and visualization of many types of data.

Gis Software Mac
1. Download from GRASS GIS website and its frameworks.
Download link: Adobe elements 9 mac download free.
For MAC OS:
mine is GRASS-7.4.4.app
2. Install all the frameworks.
After the download, you should not install it directly, but first you have to download all the frameworks.
The installation of frameworks should be in sequence according to the list of frameworks given.
3. Reinstall the python, directly from python website
Grass is compatible with python 2.7.x. Download it here
I don’t know if this is necessary, but mine could only work after this step.
4. restart your Mac in safemode and disable the csrutil
That is the complete installation procedure. next is using the rgrass7 packages in R studio so you can combine GRASS GIS with R
Download Grass Gis For Mac Windows 10
For R studio user
Download Grass Gis For Mac Mojave
Here is the sample code
Some important notice
Windows user can install GRASS GIS as a standalone program which is easier. I heard linux user also has easier experience when running GRASS GIS on their system.
When running GRASS GIS from R studio by initGRASS function, gisbase variable from the syntax is the most important.
Download Grass Gis For Mac Download
gisbase is where your GRASS lib folder listed. in my computer it is inside Application/GRASS-7.4.4.app/Contents/Resources

as our working directory is home then, you can put the name of folder “grassdata”, “nc_spm_08_grass7”, “PERMANENT”, as the gisDbase, location, mapset, respectively. All of vector and raster data of GRASS is stored inside the PERMANENT folder
