Thanks Moritz , great tip!
I'm working in a module that implemented ELECTRE algorithm.
I've just finisced a module named /r.roughset/ for knowledg discovery
with rough set based on rough set library. You can download the source
code from grass wiki
(http://grass.osgeo.org/wiki/GRASS_AddOns#r.roughset) and I'm happy if
sameone caould try it and report me tips or bugs.

Hy list,

Great news ! I'm very interested in this.
If you haven't already, you might want to have a look at the old
r.infer and r.weight modules in grass5.4. Also see the GRASS news
article by Peter Löwe: http://grass.itc.it/newsletter/grassnews3.html.
Just one suggestion: it might be worthwhile thinking about error
handling/propagation in such a module...
I've a problem with doublevalue multiple answers processing.
The code is like that:
"
/weight = G_define_option();
weight->key= "weight";
weight->type = TYPE_DOUBLE;
weight->required = YES;
weight->multiple = YES; weight->description = _("Criteria
weight(s) (w1,w2,..)");/
"
I'd like extract single value so, I tried this:
"
/for(i=0;ianswers[i]);
}/
"
Not sure, but I think the ->answers are always string, so you have to
transform to float with atof:
G_message(_("Peso %d : %lf"),i,atof(weight->answers[i]));

I'd like extract single value so, I tried this:

but the value is always 0..
I'm not a guru. Is there anybody so patient to help me?
Thanks

P.S. I'm afraid this is the second message posted to list. Exuse me!

Re: [GRASS-user] Compiling addons from svn repository
If you install GRASS with "sudo apt-get install grass" this does everything for you and you don't need to compile anything. Although you could get also the source with apt-get (don't know exactly how right now and where it will be placed), you can decide to create a source directory for all of your "geo-source codes" (e.g. /home/nik/source or /usr/local/src --- it doesn't matter I think where it is but you have to give full read-write-execute access to your login) and "draw" the source codes with svn as it is described in [1]: svn checkout https://svn.osgeo.org/grass/grass-addons grass-addons Another "svn" example is: svn checkout https://svn.osgeo.org/grass/grass/trunk grass_trunk This will get the trunk(=grass7) source code and put it in a directory called "grass_trunk" (look at last argument of the above command) within the directory from where you execute the command. So if you are currently in /home/eduardo the "grass_trunk" directory will be created in /home/eduardo.

[...] Assuming you have a working grass installation and you have downloaded the grass-addons, enter the grass-addon directory of you interest (for example if you want to install i.pr): cd /your-path/grass-addons/imagery/i.pr/ Next you have to point "make" to the GRASS installation directory (not the source!), something like: make MODULE_TOPDIR=usr/local/grass-6.4.svn Finally you have to re-run "sudo make install" from within the GRASS-source directory. That should do it. Greets, Nikos P.S. I can't get i.pr working. I've read the help files and the tried the example commands but I always get a Black image when I run i.pr_training.

[GRASS-user] Compiling addons from svn repository
Dear all: I would like to install an add-on for GRASS 6.3.1 called i.pr that appears to be available on the svn repository. I never used the svn repository so I find it a bit challenging (I cannot fully understand the instructions on http://www.hpcc.nectec.or.th/grass/download/addons.php). Could anyone tell me which code should I write at the bash in order to download and compile the add-on? (any detailed link would do). Thank you very much Eduardo Corbelle PS: I'm not sure whether it is relevant, but I'm running grass on Debian Lenny and I have the Subversion client installed. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
