[R-sig-Geo] RSAGA and a custom module

[Alexander Brenning]

Hi Ludwig,

RSAGA functions - including rsaga.get.usage and rsaga.get.modules - use the saga_cmd command line interface to access modules. So if saga_cmd was able to see your module, so should RSAGA. Is it possible that your module isn't fully integrated into saga_cmd? If that's the case, you may want to discuss this issue in one of the forums on the SAGA GIS sourceforge project website
http://sourceforge.net/projects/saga-gis/

On the other hand, rsaga.get.libraries actually just lists the names of all .dll files located in the (default or specified) modules folder. So if your library is not included in that list, maybe your folder settings are incorrect? Most RSAGA functions take an 'env' argument, which is a list that is populated through a call to rsaga.env(); you may specify a 'modules' path in the rsaga.env call. Similarly, rsaga.get.libraries takes an optional 'path' argument that specifies where to search for libraries.

I hope this helps
  Alex

Dear list,

A colleague of mine has written a SAGA module doing a Cut/Fill calculation
(which works fine from SAGA GUI) and I want to use it from within R. I have
copied the *.dll of the module to the modules folder of SAGA. I successfully
connect to SAGA but then I cannot find the module (i.e. using
rsaga.get.modules() or rsaga.get.libraries()). Is there a way to use
self-made modules with RSAGA? This is SAGA 2.0.6.

Thanks a lot in advance,

Ludwig
