simple source policy routing not working
Hi,
my box is connected to 3 networks, eth0 eth1 wlan0. I want "my" traffic to go
via wlan0 and everything from eth1 NATed to eth0:
eth0 192.168.1.10/24
eth1 172.16.1.1/12
wlan0 192.168.10.190/24
I first tried this with two single hosts:
iptables -A POSTROUTING -j MASQUERADE -o eth0 -t nat
iptables -A POSTROUTING -j MASQUERADE -o wlan0 -t nat
echo 200 Forw >>

Problem with optim()
I am having a problem with optim() using the "L-BFGS-B" method. When I
set the lower limit for the third parameter equal to zero I get an
error message:
> low.lim.3 <- 0

Log rank test power calculations
Does anyone have any ideas how I could do a power calculation for a log
rank test. I would like to know what the suggested sample sizes would
be to pick a difference when the control to active are in a ratio of 80%
to 20%.
Thanks
Dan

Samba closing printer prematurely?
Greetings Samba Users,
I have a strange issue. Adobe Reader can't print to a Samba
printer. It would be funny except it is happening to me....
Adobe Reader can't print PDF files to a true Adobe PS3 printer but GhostView can
print PDF files without any problems.
The printer in question is a Ricoh Aficio AP4510.
I tried Samba v3.0.11 and v3.0.20 and I get the same result, no

This is certainly a bug.
There are two problems:

Forward Stepwise regression with stepAIC and step
Dear all,
I cannot seem to get the R functions step or stepAIC to perform forward
or stepwise regression as I expect. I have enclosed the example data in
a dataframe at the end of this mail. Note rubbish is and rnorm(17) variable
which I have deliberately added to the data to test the stepwise procedure.
I have used

lpSolve constraints don't seem to have an effect
Dear R users,
I would like to optimize a linear approximation of a quadratic function
using lpSolve. My code runs without any error or warning message but the
constraints that I set don't seem to work properly.
Nevertheless, I am certain that my code is somewhere wrong.
I would like to solve the following problem:
max 2x-x^2+y
subject to
2x^2 + 3y^2 <= 6
2>= x,y >= 0

functions
I wrote some functions for multiway CANDECOMP, i.e. for least
squares fitting of
a_{i_1\cdots i_m}\approx\sum_{s=1}^p x^1_{i_1s}x^1_{i_1s}\cdots
x^m_{i_ms}
with arrays of arbitrary dimension. Reminded me of the good old APL
days. I could not find this in the archives, but if it's already there,
I would appreciate if someone let me know.

code optimization tips
Hi,
Being new to R I'm asking for some advice on how to optimize the
performance of the following piece of code:

Fitting a kind of Proportional Odds Modell using nlme, polr, lrm or ordgee
Hello,
I'm trying to fit a special kind of proportional odds model from:
Whitehead et al. (2001). Meta-analysis of ordinal outcome using
individual patient data. Statistics in medicine 20: 2243-2260. (model 2)
The data are as follows:

library(geepack)
library(Design)
library(MASS)

Greetings. I have a question with mixed beta regression model in nlme.
*Dear R-help:
My name is Rodrigo and I have a question with nlme package
in R to fit a mixed beta regression model. The details of the model are:
Suppose that:*
*j in {1, ..., J}* *(level 1)*
*i in {1, ..., n_j}* *(level 2)*
*y_{ij} ~ Beta(mu_{ij} * phi_{ij}; (1 - mu_{ij}) * phi_{ij})
y_{ij} = mu_{ij} + w_{ij}
*
*with*
*logit(mu_{ij}) = Beta_{0i} + Beta_{1i} * x1_{ij} + b2 * x2_{ij}

Greetings. I have a question with mixed beta regression model in nlme (corrected version).
*Dear R-help:
My name is Rodrigo and I have a question with nlme package
in R to fit a mixed beta regression model. I'm so sorry. In the last
email, I forgot to say that W is also a unknown parameter in the mixed
beta regression model. In any case, here I send you the correct formulation.

nomianl response model
Is there a way to estimate a nominal response model?
To be more specific let's say I want to calibrate:
\pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m
e^{\xi_{h}+\lambda_{h}\theta_j}}
Where $\theta_j$ is a the dependent variable and I need to estimate
$\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$.
Thank you,
