hi! i send again my question because there was a problem earlier that someone did not see my attached file. If you really can't download it, this is the attached file. Please help me how to convert this S plus file to R. Is there a quick method to do it? I don't have an S plus installer here. --------------------------------------------------- # Computes a possible choice for

Two nights ago I took a leap and extended my testing of dovecot 1.1 by replacing 1.0 for the approx 15 users I had on 1.0. At that time I also for the first time tried dovecot 1.1 in a load balanced 2 server configuration with indexes on NFS. I was hoping I did this right, using the mail_nfs params and 1.1 so fchown etc would flush the access cache, but I am getting a number of messages and

I would guess this is unlikely to be dovecot's fault, but I'm wondering if anyone has any ideas of what might have happened based on the evidence. My best guess is some kind of resource limit was reached but I don't see any evidence in the logs, and the condition is now gone. Suddenly this morning, one (and only one) of my dovecot servers decided to start failing all logins since

This happened a while back, I was running 1.1rc3 up until today so I have no idea if it would have an effect. Sorry if its something that has been fixed. The error below was repeated many many times, I deleted the index so the user would stop getting disconnected (although I didn't hear any complaints). I have not seen this happen repeatedly in this manner to any other user yet. Apr 15

Hi, I'm having trouble with an IRQ conflict I can't figure out how to resolve. I tried KDE (which is great), but this required the NVIDIA driver. However, this driver conflicts with my modem. If the driver is loaded, then the system locks up when accessing the modem. If I remove the NVIDIA driver from /boot/loader.conf, modem works fine. I tried moving the modem to different slots, but

It has always been my understanding that deviance for GLMs is defined by; D = -2(loglikelihood(model) - loglikelihood(saturated model)) and this can be calculated by (or at least usually is); D = -2(loglikelihood(model)) As is done so in the code for 'polr' by Brian Ripley (in the package 'MASS') where the -loglikehood is minimised using optim; res <-

Hello all, I have an ordered factor that I would like to include in the linear predictor of a binomial glm, where the estimated coefficients are constrained to be monotonic. Does anyone know how to do this? I've tried using an ordered factor but this does not have the desired effect, an (artificial) example of this follows; n <- 100 strings <- sample(c("low",

Dear all, Recently I am generating large random samples (10M) and any duplicated numbers are not desired. We tried several RNGs in R and found Wichmann-Hill did not produce duplications. The duplication problem is the interesting birthday problem. If there are M possible numbers, randomly draw N numbers from them, the average number of dupilcations D = N(N-1)/2/M. For Knuth-TAOCP and

...;s been a life saver for me many times. However, I think I've discovered a bug. It seems that, when I use weights during an initial least-squares regression fit, and later try to add terms using stepAIC(), it uses the weights when looking to remove terms, but not when looking to add them: hills.lm <- lm(time ~ dist + climb, data = hills, weights = 1/dist2) small.hills.lm <- stepAIC(hills.lm) stepAIC(small.hills.lm, time ~ dist + climb) In the first stepAIC(), it says that the AIC for the full "time ~ dist + climb" is 94.41. Yet, during the second stepAIC, it says adding...

Hi all, After some research I've found that this device should run with the blazer_usb driver.

Starting with example Wichmann-Hill code from Brian Ripley I have been playing with a set of programs for getting the same random sequences from R and Splus. A copy is included below along with a test (which works in Solaris with R and Splus 3.3). The approach is somewhat different from the usual problems on this list as I am trying to get the same results from Splus as I get from R. However,

I am running R 1.2.1 under Windows 98SE. termplot() currently fails when there are composite terms, thus: > library(mass) > data(hills) > hills.lm <- lm(time ~ climb + poly(dist, 2), data = hills) > termplot(hills.lm) Hit <Return> to see next plot: Error in eval(expr, envir, enclos) : Object "dist" not found The call > termplot(hills.lm,data=hills) does run without generating an error messag...

Hello all, I am generating large samples of random numbers. The RNG help page says: "All the supplied uniform generators return 32-bit integer values that are converted to doubles, so they take at most 2^32 distinct values and long runs will return duplicated values." But I find that the cycles are not the same as the 32-bit integer. My test indicated that the cycles for

Hi Let's assume, we have a multiple linear regression, such as the one using the Scottish hills data (MASS, data(hills)): one dependent variable: time two independent var (metric): dist, climb if I am interested, after (!) fitting a lm: my. lm <- lm(time ~ dist + climb, data = hills) in the equivalence (or non-equivalence) of the two predictors "dist" and "climb":...

Dear R users, Could you please help me out. I am in trouble as I am unable to model graphs to explain the GARCH (1 , 1) model, the Hill estimator (of alpha), and the Pareto estimator. I just got introduce to R. I am working on a paper which must be worked from R. You look at the difficulty I had from the text below. [1] "DAX" "DAX_CAC" "DAX_CAC40"

I''ve been pondering how to handle our file distribution issues - we''re starting to roll puppet out, and I''d like to get it somewhat right from the start. I''ve been watching the list for a while, and observed ''complaints'' about the speed of the fileserver method when dealing with recursive directories. If I can avoid this, I''d
