Re: [GRASS-user] Help; Running Grass from R without installing GRASS

2019-04-28 Thread Mehrdad Varedi 
Thank you Micha,

I was under the impression that rgrass7 library has all the functions in
GRASS. Apparently, all it does is calling modules from GRASS and GRASS
should be completely installed on the same machine that the R code is
running. I wish at least we could connect to a GRASS copy on a web-based
VM.
I enjoyed the part of your letter that explained how to created a dataset
outside of GRASS using R code and thanks for that!

I wish it was possible to read the functions directly from a web host/cloud
instead of installing it everywhere (Even if it was a paid service it could
be an attractive option). ESRI has some API, I wish we could have it for
GRASS or I could help to write the API for GRASS.

Best regards,

Mehrdad

Re: [GRASS-user] Help; Running Grass from R without installing GRASS

2019-04-28 Thread Stefan Blumentrath 
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.

Cheers,
Stefan

Thank you for your time and sharing your knowledge Micha for the second time.

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,

i.e. I have a vector /raster file and use that to identify the region and

I have no idea.


So you're trying to run an application that's not installed? I
  can't imagine how that would work :-(. After all the libraries
  (*.dll's if this is windows) are searched for in a certain OS
  defined path. And many libraries depend on others, so the whole
  chain has to be found. 
What are the limitations on this server? Can you compile a binary
  into your home directory? If so, you might be able to install
  grass with the GISBASE in your home directory, and run from there.
  But again, GRASS has lot's of dependencies: proj4, gdal, and many
  others.  Any you need access to the compile toolchain...

 


Maybe others will have some more insight.

[GRASS-user] Help; Running Grass from R without installing GRASS

2019-04-27 Thread Mehrdad Varedi 
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?

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.

Thanks for your help and attention,

Mehrdad
