Dear All, I would like to fit some parametric survival models using left truncated, right censored data in R. However I am having problems finding a function to fit parametric survival models which can handle left truncated data. I have tested both the survreg function in package survival: fit1 <- survreg(Surv(start, stop, status) ~ X + Y + Z, data=data1) and the psm function in package

My stepAIC function works for one set of data but not another....one set of data shows the steps of eliminating variables, versus another set of data doesn't throw away any variables.

Hi, I'm getting the following error: "The mapped network drive could not be created because the following error has occured - there are currently no logon servers available to service the logon request" Any ideas?

Hi All - Quick question. Is there anyway that when a user first invokes Samba to map to a network share that they are asked to change their (samba) password. I've got a whole bunch of (samba) users who all have been given the same password and I want them to have to change it to one of their own choosing upon first login.

Dear R-devel list, R's detectCores() function internally calls "ncpus" function to get the total number of logical processors. However, this doesnot seem to take NUMA into account on Windows machines. On a machine having 48 processors (24 cores) in total and windows server 2012 installed, if NUMA is enabled and has 2 nodes (node 0 and node 1 each having 24 CPUs), then R's

Dear Tomas, thank you for looking into this. Here's the output: # number of logical processors - what detectCores() should return out <- system("wmic cpu get numberoflogicalprocessors", intern=TRUE) [1] "NumberOfLogicalProcessors \r" "22 \r" "22 \r" [4] "20 \r"

Hi, I'd like to use a flash drive as a journal device, with the purpose of keeping the main disk drive spun down as long as possible. I have a couple of questions: 1) Does the journaling code spread write accesses to the journal device evenly, as I hope, or are there blocks that are particularly "hot"? I.e., do I have to worry about the flash device dying quickly because of

Dear Tomas, thank you very much. I installed r-devel r75201 and tested. The machine with 88 cores has NUMA disabled. It therefore has 2 processor groups with 64 and 24 processors each. require(parallel) detectCores() # [1] 88 This is great! Then I went on to test with a simple 'foreach()' loop. I started with 64 processors (max limit of 1 processor group). I ran with a simple function

Our Invoice posting routine (intensive harddrive io) freezes every few seconds to flush the cache.

I thought that the below email would be of interest to LARTC readers. I wasted quite a bit of time tracking down this "feature" (bug?). Any comments that shed light on this would be appreciated.

Get this warning on bootup ext3 file checks on 2.6.* kernels. Apparently harmless, but how do I fix this? _______________________________________________ debian-knoppix mailing list debian-knoppix at linuxtag.org http://mailman.linuxtag.org/mailman/listinfo/debian-knoppix

Hi everyone, I tried to solve this problem but I could not find the solution. I have about 105 matrices of equal size in the memory of**R, I need to do is extract from these matrices some known positions and create a new matrix with these columns. Show you an example with only three matrices (but in my case I have hundreds of them). A=matrix(1:15,5) [,1] [,2] [,3] [1,] 1 6 11 [2,] 2 7 12

Hi all, We are observing a consistent interval of about 4 minutes at which there are large sustained writes to disk that causes mysqld to block and not respond for the entire period. We are using data=journal with a 128M journal and the filesystem is 150GB in size. We get about 300kb/sec in writes and that will jump to about 2000kb/sec during the periods of large sustained writes. Those
