Dear R users, I noticed a problem in the anova command when applied on a single coxph object if there are missing observations in the data: This example code was run on R-2.6.1: > library(survival) > data(colon) > colondeath = colon[colon$etype==2, ] > m = coxph(Surv(time, status) ~ rx + sex + age + perfor, data=colondeath) > m Call: coxph(formula = Surv(time, status) ~ rx +

Dear all, I just wrote a script to have each of my three mcmc chins running on a different computer core to improve computation speed. To do it I use the function sfLapply from the package snowfall. Before using parallell computation, I did my diagnostic analyses just after the model updating, but now I have to save the coda before. Using the CODA package, it is possible to load the outputs in a

Hello, I am trying to do arithmetic on numbers extracted from a PostgreSQL database, wherein the numbers are stored as type "money". The transcript below illustrates the problem. > Membersind06 <- sqlQuery(channel,"select * from income where rowname like '%Membersind%'") > names(Membersind06) [1] "rowname" "item"

Hello, I have written a custom LLVM Loop Pass that perforates a loop by changing the increment value for the induction variable. I am able to run this pass using the opt command and loading the shared object library from Debug+Asserts as detailed in http://llvm.org/docs/WritingAnLLVMPass.html I was wondering if this pass can be used in clang somehow. I have read about "-mllvm"

HI All, I have a data frame such as: > test x y p d [1,] 1 0 10 21 0 [2,] 2 3 11 12 0 [3,] 3 4 12 23 0 [4,] 3 5 13 24 0 and I want to perfor some operations on the first two coulums, conditional on the uneqaulity values on the 3rd and 4th columns. For instance: j = 3 test[test[,1] == j, 5] = test[test[,1] == j,2] + test[test[,2] == j,1] gives me the result: test: x y p d

Dear list members, I'd like to perform a glm analysis with a hierarchically nested design. In particular, I have one fixed factor ("Land Use Classes") with three levels and a random factor ("quadrat") nested within Land Use Classes with different levels per classes (class artificial = 1 quadrat; class crops = 67 quadrats; and class seminatural = 30 quadrats). I have four

Dear list members, First of all thank you for your helpful advices. After your answeres to my firt mail I studied a lot (R-News n?5) and I tried to perform my analysis: First, to fit a GLM with a nested design I decided to use the function "lmer" in package "lme4" as suggested by Spencer Graves and Filippo Piro. I remember to you that my data were: land use classes, 3 levels

Actually I do a similar thing. I use a VM as my home/office firewall. It works quite well and I would argue it is as secure as your standard firewall based on something like openWRT running on dedicated hardware. I also run a wireless AP in bridged mode to allow local network access on an appliance. There should be no reason that you could not put both on the same physical hardware. As for

If your laptop/server/smth is permanently wired to the internet, there's no problem to bridge this interface to the VM. But the topic starter wants to connect to the cable or wifi and still have a firewall VM. WiFi client connection with WPA(2) PSK encryption

I have seen a few suggestions on how to address the issue of a system employing both real and virtual users and domains. Is there any definitive solution as to how this should be accomplished? The system I am construction will have several hundred users, both real and virtual, and probably seven domains. I plan on using MySQL to handle the user names and passwords. -- Gerard "Seen it

Hi all. I have a very old address book application (Win95 vintage?). My wife has been using it for a long time to manage her contacts list. She likes it because it is designed to print pages formatted for her filofax-type organizer -- she has some pre-perforated stationary which gives four organizer pages per A4 sheet, and the application is designed to print directly onto this paper. We've

Hello. I'm having serious issues with ext3; any insight would be greatly appreciated: _____ Overview: I believe ext3 is supposed to be recoverable in the case of a power failure by replaying the log. However, on two separate computers (running different operatings systems too), this has been everything but the case. _____ Specifics: Sometimes, my kernel will hard-freeze and I'll

I''m building a feature for my app which allows the admin to compose an email and send it to a list of registered users (~1000). What is the best method for doing this? Should I create one email and BCC all the recipients? Is there a limit to how many recipients can be included in one email? or Should I send the same email to individual users? In the past I''ve had problems

Hi guys, Sorry for the OT. For the last couple of weeks I notice that the static in my server room is worrisomely noticeable. I cannot see what may be causing it.... Care to share some of your experience what may be the cause and the remedy? Thank you.
