I have a question about the interaction between R code and Latex language trough the Sweave function in the package "utils".
What I'm trying to do is to write a report. Contrary to the examples shown in the Sweave Manual in which table already constructed by R are "exported" on Latex files, what I would like to do is to build a table in which I combine text and

distribution of the product of two correlated normal
Hi,
Does anyone know what the distribution for the product of two correlated
normal? Say I have X~N(a, \sigma1^2) and Y~N(b, \sigma2^2), and the
\rou(X,Y) is not equal to 0, I want to know the pdf or cdf of XY. Thanks
a lot in advance.

MLE, precision
Hi, everyone
I am trying to estimate 3 parameters for my survival
function. It's very complicated. The negative
loglikelihood function is:
l<- function(m1,m2,b) -sum( d*( log(m1) + log(m2)
+ log(1- exp(-(b + m2)*t)) ) + (m1/b - d)*log(m2 +
b*exp(-(b + m2)*t) ) + m1*t - m1/b*log(b+m2) )
here d and t are given, "sum" means sum over these
two vairables.

HFSC Advanced Limiting
I am investigating changing our broadband bandwidth control scripts over to HFSC. What I would like to accomplish is this:
{ * DOWNLOAD *
I need a download class for each user (we''ll call it Class 1) that offers a minimum of lets say 384Kbps and a maximum of 1.5Mbps.
The rates between 384Kbps and 1.5Mbps should be shared among all users.
Each user should always be able to get at

Creating a contended section of bandwidth with HTB and IMQ
Hi All,
I''m trying to create a contended section of bandwidth using IMQ. I have the
imq0 device up and running, with traffic passing through it.
Firstly, I need to throttle the entire device imq0 to 2mbit/s.
I would then like to add throttle rules for individual IP addresses, allowing
them to pass up to 512kbit/s each, as long as imq0 has not reached its
2mbit/s.

add/subtract matrices, ignoring NA or missing values
Hi,
For example, given two 2x2 matrices m1 and m2. I would like to add/subtract
element by element
> m1
[,1] [,2]
[1,] NA NA
[2,] 1 2
> m2
[,1] [,2]
[1,] 1 NA
[2,] NA 2
> m1 + m2
[,1] [,2]
[1,] NA NA
[2,] NA 4
How can I ignore the NA, and get this ? Hope the solution can be extended to
subtract and modulo also.

HFSC and prioritization
I''m using HFSC to limit bandwidth for our wireless customers. However,
I''d also like the bandwidth prioritized based on packet type. This is
what I''m trying right now, and I''d just like some input from anyone out
there knowledgeable in this on whether it does what I want it to do:

I have just written a little function that takes two matrices as

matrices in upper-left position and lower-right position with a padding
value everywhere else. (function definition and toy example below). I
need nonsquare matrices and rowname() and colname() inherited appropriately.

Bridge HFSC QOS questions ...
Hello,
I''ve got somes questions about Bridge and QOS ...
I''ve got a serveur with 2 interfaces eth0,eth1 inside br0 bridge ...
nothing of special ...
If I understand all, normally I should configure TC class and qdisc on
each physical or use ebtables to manage packets on output ... right ?
I''ve attached my qos_script that hsfc and layer7 module. I use only
Iptables
