Hi all, I have the following 7 x 7 matrix. ?I am trying to figure out how to label the columns to something more descriptive other than [,1], [,2], etc. I have tried the c(x,y,z,) function, but I get a error returned stating that my vectors need to be the same length. Do I need to convert this to something else such as a list and then repack it? Thanks, Kindra ?? ? ? ? Volume Time ? ? ? ?[,1]

Hi all, I have been struggling with this one. When creating graphic devices, how do you go about resizing the output device window automatically without having to manually tinker with it to show everything in terms of tick marks and x/y lims that you specify? I have tried the aspect="" function, but that seems to only stretch the data set one way or another, and not the actual window.

Greetings, I am new to R and have been comparing CPH survival analysis hazard ratios between R and SAS PhReg. The binary covariates' HRs are the same, however the continuous variables, for example age, have quite different HRs although in the same direction. SAS PhReg produces HRs which are the change in risk for every one increment change in the independent variable. How do I

Hi there, A month ago we ran into the fsck issue while rebooting one of the Oracle RAC nodes running on Linux RHEL 5.2. It was hanging for 1.5 hours During the reboot, OS portion went fine, then it activated the data volumes in all data vg's with [OK] Then displayed message: Checking filesystems - and it took it 1.5 hrs, then it finished the reboot. Last weekend we rebooted the same box and

I am trying to merge two data frames, but one of the column headings are different in the two frames. How can I rjoin or rbind the tho frames? Johnny # Generate 2 blocks by confounding on abc d1 <- conf.design(c(1,1,1), p=2, block.name="blk", treatment.names = c("A","B","C")) d2 <- conf.design(c(1,1,1), p=2, block.name="blk",

Dear R-Helpers, I am a novice in survival analysis. I have the following code: for (i in 3:12) print(coxph(Surv(time, status)~a[,i], data=a)) I used it to fit the Cox Proportional Hazard models separately for every available parameter (columns 3:12) in my data set - with intention to compare the Hazard Ratios. However, some of my variables are in range 0.1 to 1.6, others in range 5000 to

Hi, I am working with R version 2.1.0, and I seem to have run into what looks like a bug. I get the same error message when I run R on Windows as well as when I run it on Linux. When I call anova to do a LR test from inside a function, I get an error. The same call works outside of a function. It appears to not find the right environment when called from inside a function. I have provided

Hi, I am working with a dataset for sometime and I need some help in parsing some data. There is a column called "Duration" which has data like following: 2 minutes => 120 2 min => 120 10 seconds =>10 2 hrs =>7200 2-3 minutes => 150 or 120 5 minutes (when i arrived => 300 Flyby approx 20 sec. => 20 felt like 10 mins but tim => 600 I need to convert them to

Dear R-Help, With the attached data set, I am still getting incorrect bwplots > xyplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf) # Is correct > bwplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf, horizontal=FALSE) # Puts the boxes on the wrong x-axis values # look especially at 0 and 3. How do I fix this? What is happening? Thanks, Jim Rome

I have a defective HP-Compaq nx9420 and so I am looking to replace it. I have pretty much decided to buy no further MicroSoft based products and would very much like to hear recommendations for a suitable notebook host to provide me with Linux based alternative. Given that all the basic functionality required is provided, the main thing that I am looking for is reliability of the host itself. I

Hi, I am new to time-dependent Cox model to estimate time dependent hazard ratios. Let me use aml dataset from survival package: > aml3<-survSplit(aml2,cut=c(5,10,20),end="time",start="start", event="status",episode="i") If I want to esimate hazard ratio for each of the time intervals 0-5, 5-10, 10-20 and >=20, would the following calculate

I've had this same problem. That is why I have been asking about how to remove the no-cache header. But no answer in the ether...

Dear R-Experts, seek your help. There are two parts I want to deal with. 1) I want to create a time interval of say, 30 minutes starting from "00:00:00" hrs Thus at the end, I want to create sequence: 00:00:00 00:30:00 01:00:00 01:30:00 .. .. How to do so ? Later, I want to change the time-increment value in a variable and changing the value of this variable, I would like to create

I have been googling for the RPM kernel-source-2.4.25-040218.i386.rpm or kernel-source-2.4.25-040218.i686.rpm for the last 59 hrs and couldn't succeed. Can someone suggest me some good Redhat Linux 9.0 rpm repositories. And will the Debian deb work with redhat or not?
