similar to: coxph: competing endpoints & multiple time-dependent covariate

Dear R users: Analysis of the impact of a time-dependent covariate (GVHD or use of steroid after bone marrow transplantation) on two competing endpoints (invasive fungal infection and death) is frequently encountered in the setting of BMT data. Coxph package can be used as the following: for the analysis of GVHD: > gvhd -> coxph(Surv(start,stop,status = =1) ~ GVHD, data=bmt.data)

R 2.8.1 Windows XP I am trying to plot the results of a coxph using plot(survfit()). The plot should, I believe, show two lines one for survival in each of two treatment (Drug) groups, however my plot shows only one line. What am I doing wrong? My code is reproduced below, my figure is attached to this EMail message. John > #Create simple survival object >

Hi All, I'm trying to figure out the cumulative incidence curve in R in some limited time. I found in package "cmprsk", the command "plot.cuminc" can get this curve. But I noticed that there is no mark for the censored time there, comparing with the KM curve by "plot.survfit". Here are my codes (attached is the data): ----------------

Hello, I have a problem regarding calculation of Cumulative Incidence Function. The event of interest is failure of bone-marrow transplantation, which may occur due to relapse or death in remission. The data set that I have consists of- lifetime variable, two indicator variables-one for relapse and one for death in remission, and the other variables are donor type (having 3 categories), disease

Hello R-community, I want to generate stacked density plots in lattice. My data consist of a numeric variable ('pid') that is measured in different individuals ('id'), which can be divided in two types ('type') and the measurements were repeated a different time points ('day'). I read in the Lattice book that this can be done using the 'flowViz'

Hi R-Users, I posted this question a while ago on the bioconductor mailing list but got no answers. Maybe here is somebody who might know a solution: I failed at drawing multiple filters in a densityplot() using the FlowCore/FlowViz packages. I found a way to draw multiple filters in xyplot(), using the glpolygon method within the panel-function, but some similar attempts for densityplot

Hello again, I m trying to use timereg package as you suggested (R2.7.1 on XP Pro). here is my script based on the example from timereg for a fine & gray model in which relt = time to event, rels = status 0/1/2 2=competing, 1=event of interest, 0=censored random = covariate I want to test library(timereg) rel<-read.csv("relapse2.csv", header = TRUE, sep = ",",

Dear R users, I d like to assess the effect of "treatment" covariate on a disease relapse risk with the package cmprsk. However, the effect of this covariate on survival is time-dependent (assessed with cox.zph): no significant effect during the first year of follow-up, then after 1 year a favorable effect is observed on survival (step function might be the correct way to say that ?).

Dear friends: I have just read an article entitled " Monitoring of nosocomial invasive aspergillosis and early evidence of an outbreak using cumulative sum tests (CUSUM)", which is published in "Clinical Microbiology and Infection". We have great need to estimate the fluctuation of incidence of IFI in our hospital. But I don't know the details of the stastical method and

Hello R-users: I am using "yags" for fitting GEE which is giving me the same result as "Proc GENMOD". Now I have couple of questions related to yags output. (By the way, someone told me to run the geeglm for the same analysis and I did run but did not get the same result as of genmod and don't know how to correct the geeglm codes so that all three will be same!)

Dear R-Users: I am trying to find the robust (or sandwich) estimates of the standard error of fixed effects parameter estimates using the package "lmer2". In model-1, I used "robust=TRUE" on the other, in model-2, I used "robust=FALSE". Both models giving me the same estimates. So my question is, does the robust option works in lmer2 to get the robust estimates of

Hi all, I'm trying to make a script that will shut down a couple of Windows boxes from a Linux machine with Samba. If I use "net rpc shutdown -I <windows-ip> -U administrator" it works fine, except that I get prompted for the password. After looking through "man net" I can't seem to find a way to include the password (I tried "-U

Hi all, I''ve been trying to do the above and read everything I can find on Google on the subject, but something seems to be going wrong. I tried the following sample rules in iptables (initially I just set the first one, but I added more as my desperation escalated): iptables -t mangle -A PREROUTING -p icmp -j MARK --set-mark 1 iptables -A FORWARD -p icmp -j MARK --set-mark 1

Hi all, Sorry if this is out of place, but I've seen people suggesting future functionality for Dovecot on here before. TBH I'm not completely sure if this would be possible in a LDA. Demon (an ISP) have extensions to POP3 they call "SDPS" - there's basically an extra command that can be called for an email and it gives the envelope rcpt and from addresses. I was

You're kinda confusing things there. A single physical network could span multiple IP networks, and a single IP network doesn't have to be restricted to one physical network. Do you mean that you want to use a single server to serve to two separate workgroups both of which are using the same physical hardware and IP network? If so, then I don't believe so, but I could be wrong.

Hi all, I've got a few users I'm trying to migrate from a Mercury Mail server to a dovecot IMAP/POP3 setup. I was hoping to use some sort of imap-copy type script to move email from the Mercury server to dovecot server, but the Mercury box is running so slow it's impossible. Mercury stores mail in a similar way to Maildirs, different folders with separate files for each mail, stored

Hi all, This is probably a silly question, but is there an easy way to get the dovecot executable to report it's version number?

Hi all, I'm going to be out of office for the next week (starting in the next hour or so) and I need to unsubscribe (I'm sure you don't want my out of office replies really) Can anyone help me by saving me the time it'll take to lookup the unsubscribe/resubscribe details?

Automated update system supplied with Fedora. Kinda like the RHN, but free and more up to date version-wise, but without the package checking done by Redhat. If you're running Fedora and it's installed, typing "yum update <package name>" will update a package to the latest version on your downloads site (it defaults to download.fedora.redhat.com), yum install <package
