extractAIC using surf.ls
Although the 'spatial' documentation doesn't mention that extractAIC
works, it does seem to give an output.
I may have misunderstood, but shouldn't the following give at least
the same d.f.?
> library(spatial)
> data(topo, package="MASS")
> extractAIC(surf.ls(2, topo))
[1] 46.0000 437.5059

Using VGAM's vglm function for ordinal logistic regression
R-Experts:
I am using the vglm function of the VGAM library to perform proportional
odds ordinal logistic regression. The issue that I would like help with
concerns the format in which the response variable must be provided for
this function to work correctly. Consider the following example:
------
library(VGAM)
library(MASS)
attach(pneumo)

nutdrv_qx hangs after send: QS
Thank you for the rapid response. I will try and investigate getting
answers to some of your points but I'm a little new to Solaris so I'll need
some time. Glancing at the configure output, it looks like it built against
v0.1.7 of libusb (yes i think that is derived from the one you mention),
checking for libusb version via pkg-config... 0.1.7 found

Questing on fitting Baseline category Logit model
Dear all,
I am facing some problem with how to fit a "Baseline category Logit
model" with R. Basically I am considering famous "Alligator" data as
discussed by Agresti. This data can also be found here:
https://onlinecourses.science.psu.edu/stat504/node/174
(there is also an accompanying R file, however the underlying R code
could not load the data properly!!!)

Testing proportional odds assumption in R
I want to test whether the proportional odds assumption for an ordered
regression is met.
The UCLA website points out that there is no mathematical way to test the
proportional odds assumption (http://www.ats.ucla.edu/stat//R/dae/ologit.htm),
and use graphical inspection ("We were unable to locate a facility in R to
perform any of the tests commonly used to test the parallel slopes

Wierd Networking Problem
Hi Guys,
I'm 100% sure this is not a Linux issue but I want a second opinion...
I have a Linux server running CentOS. It was been absolutely perfect
without any errors or problems.
Since Monday it has been unable to send email. It is configured to act as
a smart host. All email gets forwarded to smtp.isp.net.
The server is on a network behind a firewall completely nat'd. No ports

mounting lvm2
CentOS 7 for everything
I am probably never using lvm again. I have never not once actually
benefited from its capabilities but this is probably the third or fourth
time it has gotten in my way.
Issue is that I use the tools so rarely that I can't recall what needs
to be done to properly mount the drives on another system and finding
that info on the web is becoming more difficult as the

Solve equations
Hello,
I have a system of five equations to solve with five 'unknows'(V, W, X,
Y and Z) and constraints. The equations are:
0.007= 2VZ
0.03= W(Y+Z)
0.034= X(y+Z)
0.013 = (X+W)Y +(X-W)Z
X = W+V
Constraints:
0<V<W<X
0<Y<Z<1
Does anyone know a R-package to solve this system?
Thanks,

String.protoype.toQueryParams
Hi, I am trying to play with all the methods in the Array Object.
Just wanted to check with you guys if this is the correct explanation of toQueryParams().
If yes, then I''ll add it to the documentation as well.
Works for me (but I am not sure if it''s the correct way to use it).
/* String.prototype.toQueryParams takes a query string, i.e, string with

[PATCH 0/4] nvfx: rework render temps code and fixes
This patch series silences some unknown cap warnings and fixes up
coding style (patch 1+4).
The most important part of this series are the two patches in the
middle. They rework the state_fb code, so that we are able to
render to not 64 byte aligned targets, as this is the only real
use-case for render temporaries this allows us to drop temp code
completely and simplifies a lot
