Hi Mehrdad, If this is a permission issue, and the dependencies (and a build environment) are installed, you could try compile GRASS (and install it in your home directory if necessary with the --prefix configure option). svn checkout https://svn.osgeo.org/grass/grass/ grass_trunk cd grass_trunk ./configure make make install The make install step is not required for starting GRASS though. The make commando creates a bin…/ directory within the grass_trunk dir, where the grass startupscript is located…
Hope that helps.

I followed your code and found that initGRASS searches for libraries and binaries of GRASS in gisBase folder. If we address a folder that doesn't have the code it comes back with this error message: "The code execution cannot proceed because libgrass_gis.7.4.1.dll was not found. Reinstalling the program may fix this problem." it gives the same error even if I copy that file into GISBase folder. I want to run my code on a shiny server which I can't install GRASS although I can copy files and libraries. Can I solve this issue by copying a certain folder of GRASS binaries with my app or I am going the wrong path? Please advise, Thank you once again for all the time you share to answer my questions, Mehrdad [https://mailfoogae.appspot.com/t?sender=admFyZWRpQGdtYWlsLmNvbQ%3D%3D&type=zerocontent&guid=6036490f-455f-4578-9a0d-ec0122c7134a]ᐧ On Sun, Apr 28, 2019 at 10:55 AM Micha Silver <[email protected]<mailto:[email protected]>> wrote: On 27/04/2019 22:05, Mehrdad Varedi wrote: Hi Everyone, I have detail explanations of connecting to an existing dataset in GRASS from R in this address: https://grasswiki.osgeo.org/wiki/R_statistics/rgrass7 What I hope I could do is to create a GRASS dataset in R on the fly and without the need to install GRASS or create a dataset on it. Is there any way to do this? Maybe this will help: (You must have GRASS installed, of course) # Parameters for the GRASS installation and temporary GRASS mapset GISBase = "/usr/lib/grass76" # Set these as you like GISDbase = "/tmp" Location = "tmp_location" Mapset = "tmp_mapset" georef = "EPSG:2039" mapset_path = file.path(GISDbase, Location, Mapset) # Now run the 'grass' command within R and # use the -c and -e flags to create the temp mapset, then exit setup_grass_cmd = paste("grass", "-c", georef, "-e", mapset_path) system(setup_grass_cmd) # Load the R grass interface and initialize GRASS within R, # using the temporary mapset from above library(rgrass7) initGRASS(home=tempdir(), gisBase = GISBase, gisDbase = GISDbase, location = Location, mapset = Mapset, remove_GISRC = TRUE) # Try some GRASS commands input_tif = "isrlat12.tif" grass_rast = "isrlat12" execGRASS("r.in.gdal", flags = c("o","overwrite"), input = input_tif, output = grass_rast) execGRASS("g.region", flags="p", raster = grass_rast) I did not add a command to remove the temporary mapset. Something like: unlink(file.path(GISDbase, Location), recusive = TRUE) might be necessary One other note: you probably will get better suggestions on the R-sig-geo list... i.e. I have a vector /raster file and use that to identify the region and details required to set up a dataset and use GRASS functions just by including rgrass library.
