Re: [Qgis-user] Classification in R (Off Topic)

[MacQueen, Don]

The most appropriate forum would be:

__
r-h...@r-project.org mailing list -- To 
UNSUBSCRIBE and more, see
https://stat.ethz.ch/mailman/listinfo/r-help
PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.

The help page (in R) should give some indication of what "OOB" means, or 
perhaps provides references that will (I myself do not know).

Subject: [Qgis-user] Classification in R (Off Topic)

Hello, this is not the right forum, but I appeal to the community:

I made a process using R, changing only inputs and outputs to generate a 
supervised classification and gives me the following data at the end:

Calculating random forest object
Starting predictions
#
OOB error rate estimate
0.007407407%

Confusion matrix
1   2   3  4 class.error
1 101   0   0  0 0.0
2   0 101   0  0 0.0
3   0   0 101  1 0.009803922
4   0   1   1 99 0.019801980

Hello, this is not the right forum, but I appeal to the community:

I made a process using R, changing only inputs and outputs to generate a 
supervised classification and gives me the following data at the end:

So: 1. What does OOB mean in itself? 2. In what range or interval should the 
OOB value be so that the prediction is better?

Thank you

[Qgis-user] QGIS 3.2 installer doesn't find Python 3.6 on Mac?

[MacQueen, Don]

Hi,

I have (finally) upgraded my MacOS to 10.13.5, and am reinstalling/updating 
various apps, including QGIS.

When I try to install QGIS (step 3 on the QGIS dmg, after having done steps 1 
and 2 in order), I get the message
   "QGIS requires Python 3.6"

Apparently, the QGIS installer isn't finding the newly installed Python 3.7. 
Strikes me as a path problem. I'd appreciate help solving it.

Thanks!
-Don


More detail:

I downloaded
   QGIS-macOS-3.2.0-1.dmg
from the QGIS website, and followed its instructions in order, including
  1. install Python 3
  2. Install GDAL complete

I first installed Python from
   python-3.7.0-macosx10.9.pkg
which I found following the links in the step 1 readme.
I ran the 
   "Update Shell Profile.command"
script provided with Python3.
I then installed GDAL complete.

After having done all that:

In Terminal.app, I get

[8]% which python3
/Library/Frameworks/Python.framework/Versions/3.7/bin/python3

[9]% which python
/usr/bin/python
[10]% python --version
Python 2.7.10

I have tried logging out and logging in, and even restarting. Didn't help.

Re: [Qgis-user] Connecting a bluetooth Garmin GPS to a MAC for live tracking in QGIS

[MacQueen, Don]

Well, I really don’t know … but based on ancient experience with connecting a 
data logger to a Mac serial port, I looked in /dev on my Mac.

ls /dev
   …lots of entries, among them is:
   tty.Bluetooth-Incoming-Port

So maybe that can be used somehow…

Hi !

Well, the title says it all !!! I am trying to connect a Garmin 3580LM GPS unit 
via bluetooth so QGis can use it…Paired OK with Mac, cannot find serial port 
number, as neither Autodetect or Serial works…

Any help appreciated !

[Qgis-user] How to specify a local coordinate system

[MacQueen, Don]

I'm using QGIS to display drawings that come from CAD files (dxf). They
are in a local cartesian coordinate system with a local origin, not
related to any coordinate system known to PROJ4.

How should I specify the coordinate system when I read the dxf file into
QGIS (using Add Vector Layer)?

I suppose I'm looking for something analogous to what GRASS happens in
GRASS, in the Define new GRASS Location wizard, with the Create an
arbitrary non-earth coordinate system (XY) option.

Thanks
-Don
