I find this odd because it doesn't appear to happen in larger datasets. I have the following data set ENV with the first column set as row.names: > ENV TPlog 001S29H 0.601 002S42H 0.602 003S43S 0.779 004S43S 0.702 005S51H 0.978 006S52P 2.718 If I apply > ENV <- ENV[-1,] # remove first row of data (right?) ...ENV comes back as: [1] 0.602 0.779 0.702 0.978 2.718 So I

Hello: In the example below (or for a censored data) using survfit.coxph, can anyone point me to a link or a pdf as to how the probabilities appearing in bold under "summary(pred$surv)" are calculated? Do these represent acumulative probability distribution in time (not including censored time)? Thanks very much, parmee *fit <- coxph(Surv(futime, fustat) ~ age, data = ovarian)*

Hi, I'm running GEE using geepack. I set corstr = "ar1" as below: > m.ar <- geeglm(L ~ O + A, + data = firstgrouptxt, id = id, + family = binomial, corstr = "ar1") > summary(m.ar) Call: geeglm(formula = L ~ O + A, family = binomial, data = firstgrouptxt, id = id, corstr = "ar1") Coefficients:

Hello R-help subscribers, I am analyzing a data set using a mixed logit model, and I have recently discovered some curious behavior. I am hoping you all can help. I first ran the following model in December 2012. lmer(Response.binary ~ ItemType.c * Block + (1 | Subject) + (1 | Word), data=lexdec, family="binomial") I then took a break from the data for the holidays. I returned to

It's probably PR12517. Looking at the clang binary, it's got a /home/ dir in RPATH: $ objdump -p clang+llvm-3.3rc3-Ubuntu-12.04.2-x86_64/bin/clang | grep RPATH RPATH $ORIGIN/../lib:/home/aadgrand/tmp/LLVM-3.3rc3/rc3/Phase3/Release+Asserts/llvmCore-3.3-rc3.obj/Release+Asserts/bin This will slow things down if the system tries to automount /home/aadgrand. Maybe we should merge r182559

Hi Bill, I was running some benchmarks and was surprised that the startup performance of your binaries is much worse than the stable binaries for 3.2 I've used: http://llvm.org/releases/3.2/clang+llvm-3.2-x86_64-linux-ubuntu-12.04.tar.gz vs http://llvm.org/pre-releases/3.3/rc3/clang+llvm-3.3rc3-Ubuntu-12.04.2-x86_64.tar.gz On a simple hello.c file: /ssd/bench$ TIMEFORMAT="%E"

Hi LLVM-ites! We are doing a quick test of 3.3rc3. Our testers did a quick turn around and created binaries which you can test. Please give them a go and let us know how they work for you. They are here: http://llvm.org/pre-releases/3.3/rc3 We don't have a lot of time remaining in the release cycle, so please do whatever you can to make sure they are solid. In particular, make sure that

Until a weeks ago I used stata for everything. Now I'm learning R and trying to move. But, in this stage I'm testing R trying to do the same things than I used to do in stata whit the same outputs. I have a problem with the logit, applying weights. in stata I have this output . svy: logit bach job2 mujer i.egp4 programa delay mdeo i.str evprivate (running logit on estimation sample)

Dear Researchers, Sorry for this email but I am not a statistician, and for this I have this problem to understand. Thanks in Advance for help and suggestions. Gianni I have 21 classes (00, 01, 02, 04, ....,020) with different length. I did a kruskal wall test in R with the following code kruskal.test(m.class.l, m.class.length.lf) Kruskal-Wallis rank sum test data: m.class.l and

I'm not sure I follow. Will the final binaries have a bad RPATH or not? A 1sec startup pause on some (admittedly crazy) systems seems like a big deal to me.

Hi there, This problem has been dogging me for a bit, and I'm trying to figure out why. When running the the subsets function in the leaps library, R is giving me the following error message > lvodsub <- subsets(pred, resp$LVOD) Warning message: XHAUST returned error code -999 in: leaps.exhaustive(a, really.big = really.big) but this still happens if I add the really.big option:

Beyond a general problem with X11, that it sometimes doesn't display -especially when it is inactive for a while- new windows (like new terminal, R device, or emacs) and only the restart helps, I found a problem which might also be especially the X11's problem. >From an apple Terminal window, the following code (which is the first boot.ci example) works just fine.

Hi,. We have 2 values (first formant F1, second formant F2) for a given phoneme for six languages. We want to see whether the languages are significantly different one from another for this given phoneme. We have done a manova on our data and it works well, but we doesn't allow us to see which pair of languages are different. If we have only one formant for the phoneme, we would use

setTimeLimit(elapsed=1) causes a timeout error whenever a call takes more than one second. For instance, this is how it works on Windows (R 3.3.1): > setTimeLimit(elapsed=1) > Sys.sleep(10); message("done") Error in Sys.sleep(10) : reached elapsed time limit Also, the error propagates immediately and causes an interrupt after ~1 second; > system.time({ Sys.sleep(10);

I am using the coxph, survfit and summary.survfit functions to calculate an estimate of predicted survival with confidence interval for future patients based on the survival distribution of an existing cohort of subjects. I am trying to understand the calculation and interpretation of the std.err and confidence intervals printed by the summary.survfit function. Using the default confidence
