Hi, we're running the standard linux bridge setup (redundant bridge) for 5 years now. So first of all, thanks to everyone involved for implementing the bridging feature in Linux. Now I'm trying to bridge hosts connected to VLAN'ed Cisco switches using linux bridge. I'm testing the following setup (Kernel 2.6.19, bridge-utils 1.2 on both bridges)

I am doing some testing of openwrt'd wireless access points, using madwifi-ng'd atheros radios. In the test configuration, I have three devices in a triangle, each has wds links to the other two devices. The ath0 interface is in ap mode, ath1 is a wds link to one device, and ath2 is a wds link to the other device. All three interfaces (and an ethernet interface) are in a bridge (br-lan)

Dear Listers I have tried to install Frank Harrell's two libaries: Hmisc and Design. I found that Hmisc was listed in the list of packages from the Install Packages command on the Packages menu, but Design was not. I installed Hmisc from this list, and when I issued the library(Hmisc) command, it loaded into memory correctly. I then copied the Design 1.1-1.zip file from the

Dear All, there seems to be some strange influence of the Design package on data.frame. If I build a data.frame containing a Surv object without loading the package Design, the data frame is usable to coxph. If instead I just load Design and build a data.frame afterwards, the naming of the Surv object is different and it does not work with coxph. (In my real application I loaded Design to use the

Hi, i need to create a fractional factorial design sufficient to estimate the main effects. The factors may have any number of levels, let's say any number from 2 to 6. I've tried to use the library conf.design , but i cannot figure out how to write the code. For example, what is the code for a design with 5 factors (2x3x3x5x2) and only main effects not confounded? thanks in advance!

Dear all, I'm working on a design with rotating panels. Each site is sampled every X year. Have a look at the code below the get an idea of the design. In reality the number of sites will be (much) higher. However I'm not sure if I coded the design correctly in svydesign(). Can someone confirm that it is either correct or wrong? I've added the lmer() equivalent that I want to

...So I advertised on craigslist, and in a few web design forums (in the jobs section). I''ve had easily 100 replies (mostly craigslist), here''s my breakdown: 80 offshore sweatshops, who would be delighted to butcher my site with table based, flash ridden "eye catching" designs 5 front page/dreamweaver users who would be equally delighted to charge me for pressing a few buttons 5 developers who dont even mention design, xhtml or css in their email but who still want to work for me 4 developers who genuinely get css/accessibility but who are clearly developers and not d...

I am considering trying Rails out on a small web project where I will be working with a designer. What is the typical workflow and relationship for this: 1 have the designer learn rhtml or 2 have the programmer take html mock ups and turn them into rhtml In the past I have used Django (also very nice), which has a fairly accessible (ala php) templating language. Thanks, David S. -- Posted

Hi, I've searched through the contributed packages and found conf.design which supports factorial design generation - is there any way to specify the values of the levels in the functions in this library? Currently the default for 2 level designs are the levels 0 and 1. Reason I ask is I'd like to create a Central Composite design and to do this by appending to a factorial design, it would be easiest if the levels of the factorial were at -1 and 1... (so I can add levels such as 0, -2 and 2) This brings me to my second question - is...

Hi, I'm running into an error message for the "anova"-function I never got before with the Design (Version 2.2-0) package. There seems to be a missing function "Varcov", please check my function calls (it's in german but I think you get the error): > library(Design) ## attaching Design package and dependent packages Lade n?tiges Paket: Hmisc ## loading

Hi all, Does anybody know if it is possible to build a fractional factorial design in R? That is, suppose that we want do design an experiment with 3 factors with 2, 3 and 3 levels, respectivly. However we want to consider, let's say, only 6 from all possible level combinations. Does R design such experiment? Thanks in advance, Caio [[alternative HTML version deleted]]

Okay, this applies particularly to SYSLINUX, not ISO/PXE/EXTLINUX. If you have a system on which 2.13 boots and 3.0x don't, I would like to get as much information as possible about it. In particular, I would like to know: - What device are you booting from (floppy, USB, IDE harddrive...) - Motherboard manufacturer/model - CPU manufacturer/model (a dump of /proc/cpuinfo would

R-help, Sorry for this question (I guess it has been addressed before but I could not find it in the archives) but how can I see a function code when the following comes up: > svymean function (x, design, na.rm = FALSE, ...) { .svycheck(design) UseMethod("svymean", design) } <environment: namespace:survey> Thanks in advance

Dear developeRs, I just discovered the function plot.design in package graphics that acts as a method for class design - the second time I come across a class design outside my own packages. (The first time was in package conf.design, where Bill Venables encouraged me to ignore it because he does not really use it.) Where can I find out more about the nature of the class design for which

Gents, We''re hard at work on a new Rails app. We''re a small group of developers...not a web designer in the bunch. We know CSS enough to be dangerous, but we shy away from the "softer" skills (all the while envious of those with that capability). We intend to grow our application in terms of functionality, but I need to make sure we keep an eye towards

Dear all, I am trying to find a R version of the S+ routine fac.design. In the help of the package conf.design fac.design is listed under "see also". Any clues as to where (which package) I can find fac.design? thanks Steve.

The Design library has been fully ported to R except for Cox proportional hazards regression modeling (using Therneau's survival package) which will be available in about two weeks. It will take much longer to make all the example code executable, is it currently contains many examples for which data are not provided. Thanks to Xiao Gang Fan <xiao.gang.fan1 at libertysurf.fr> who

I am still a little unclear in the difference between randomized block design and two-way factorial design after consulting a few books, including John Rice Mathematical Statistics and Data Analysis. Both put observations in cells corresponding to two factors of many levels. Both use the same computer program to analyze data. It seems that randomized block design can have only one observation

Hi, I have some problems when using AlgDesign->optFederov() generating designs. I have 6 variables, all factors. 3^2 and 4^4, I want to have a design that can take care of main effects and two interactions within 2 pair of variables v3-v4 and v5-v6, the following is the code ################ require(AlgDesign) set.seed(1) levels = c(v1=3,v2=3, v3=4,v4=4,v5=4,v6=4) dat&l...
