I made some contour lines with r.contour. AFAIK, these are vector lines. But I cannot edit them in the digitizer. When I click on a vertex, nothing happens. I can make and edit other lines, but not contour lines. No error in the console either. Anyone know
why?

<br>
For sure. There are two _good_ grassy-sources to start with:<br>
<br>
1. the i.pca's manual<br>
http://grass.osgeo.org/grass70/manuals/i.pca.html<br>
<br>
2.the GRASS-Wiki page explains all one needs to know -- even if it requires <br>
some clean-up<br>
<http://grasswiki.osgeo.org/wiki/Principal_Components_Analysis><br>
<br>
And, of course (sorry for insisting and self-advertising) my work (available <br>
at the link I've PMed to you). I've put a lot of effort to compile material & <br>
explain what PCA is, what it does and how it does it. It would be really <br>
nice, for me, to have some feedback if it helps, in any way, to understand <br>
PCA.<br>
<br>
If you had a look and found the material useless, please, be so kind and tell <br>
me so -- strait (PM or ML, the same). I'd really like to know what you think <br>
as I am planing to continue this effort in time, and expand it.<br>
<br>
Best, Nikos<br>

@Michael, @William<br>
<br>
I did what I describe(d) above and, with the help of AnnaK, we got the GUI <br>
running.<br>
<br>
Yes, 2.7 and 2.9. It may be that it bears other, non-desired, sideeffects or <br>
dangers (?). However, I never really use OS-X and since the GUI is launching, <br>
we can go bug-hunting.<br>

Thanks, Nikos<br>

#1874: latitudinal bias in sample points created with r.random<br>

Reporter: pvanbosgeo | Owner: grass-dev@… <br>
Type: defect | Status: new <br>

Replying to [ticket:1874 pvanbosgeo]:<br>
<blockquote type="cite">Note that points created with v.random do no show a bias.<br>
However, this is not really an alternative for creating<br>
random points within a irregular area.<br>
</blockquote>
<br>
the v.random.cover addon script for grass 6 exists to do that.<br>
http://grasswiki.osgeo.org/wiki/AddOns/GRASS_6#v.random.cover<br>
<br>
'' v.random.cover is a shell script for creating random points constrained<br>
within an irregularly shaped vector area. (v.random places points only in<br>
current region rectangle). Optionally the user can upload raster values at<br>
the points. See also 'r.random cover= vector_output=' ''<br>
<br>
<br>
It's internal method is not especially efficient, but it gets the job done<br>
all the same.<br>

That's very good that wxPython 2.9 runs. My hope has been that with a bit of tweaking it would work. So I'm glad that you've had time to try it out. Thanks much.<br>

I can compile grass_trunk which ends up with various wxpython related<br>
errors. So, the gui wont launch. Could it be that we only need to<br>
properly install<br>
<br>
- python 2.7<br>
<http://python.org/ftp/python/2.7.3/python-2.7.3-macosx10.6.dmg> - wxpython<br>
2.9 (the cocoa build)<br>
<http://downloads.sourceforge.net/wxpython/wxPython2.9-osx-2.9.4.0-cocoa-py2<br>
.7.dmg><br>
<br>
and then set up properly GRASS to pick those up?<br>

<br>
@Michael, @William<br>
<br>
I did what I describe(d) above and, with the help of AnnaK, we got the GUI <br>
running.<br>
<br>
Yes, 2.7 and 2.9. It may be that it bears other, non-desired, sideeffects or <br>
dangers (?). However, I never really use OS-X and since the GUI is launching, <br>
we can go bug-hunting.<br>
<br>
Thanks, Nikos<br>

<br>
keep in mind that the shared VM that it is run on is generally<br>
under considerable load (but not at capacity), and anything extra<br>
on top won't help that situation. Maybe we could put a nightly<br>
build on the adhoc VM and keep the existing one once a week?<br>
