Hello all! As beginner I'm struggling for a while with time zones issue and can't find a suitable solution. I would be grateful for any help.

I would be very grateful if someone could help me with this, to be able to move on.

Dear All: I am using lmer() {lme4} to analyze results from a reciprocal transplant experiment where the response variable is modeled as a function of two fixed effects and their interaction. Example data follow: #library(lme4) #library(gmodels) env=c("r","r","w","w","r","r","w","w","r",...

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 type(having 3 categories), disease stage...

All, I'm trying to analyze the results of a reciprocal transplant experiment using lme(). While I get the error-term right in aov(), in lme() it appears impossible to get as expected. I would be greatful for any help. My experiment aimed to identify whether two fixed factors (habitat type and soil type) affect the development of plants. I took soil from six rand...

Hi all, I've a 30TB hardware based RAID array. Wondering what you all thought of using ext4 over XFS. I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions. This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files. - aurf

...led on p.65 of: http://cran.r-project.org/web/packages/survival/survival.pdf My data (used in my study) is 'right censored' i.e. my variable corresponding to 'event' indicates whether a person is alive (0) or dead (1) at date last seen and my 'time' indicates time from transplant to date of last contact (where this is time from transplant to death if person has died or time from transplant to date last seen if person is still alive). Now I am using function, rcorr.cens http://lib.stat.cmu.edu/S/Harrell/help/Hmisc/html/rcorr.cens.html This function involves use of Surv....

Dear R user, I'm relative new and need some help / advise from you. I have organised my data in several frames, mainly because the data came from different sources. One common variable in all data frames is the day post transplantation. I would like to combine the data frame to one big data frame which contains all the data, however no duplicate rows should occour (only one row for one day) Here an example which illustrates what I would like to do: Frame 1 Day Hb wbc 1 10 4 3 11 7 5 9 6...

I want to essentially transplant my existing Asterisk server to a new machine, and take the old sever out of service.

Hi all, Recently I have implemented a transformation pass based on LLVM3.5 and its function is to duplicate the function's argument list in a bytecode file and replace all use of original function with modified function. In LLVM3.5, the pass can work properly. However, when I tried to transplant the pass to LLVM3.9, the error "Argument value does not match function argument type!" occured. The core snippet of my pass is as follows: 'func' denotes original function in a Module; 'new_return_type' denotes the duplicate of original function's return type; 'ar...

...a non-randomized cohort, is there a way to estimate the treatment effect? (i.e., after joining the study, some patients may have to wait for a period of time before receiving the treatment, i.e., the situation of patient with id == 2 for the following data) Data format is like the stanford heart transplant data (Therneau et al 2000, p69), but the patients were not randomized in selection and the covariate balance is not achieved: id time censor tx x1 x21 (0,10] 1 0 x11 x122 (0,8 ] 0 0 x21 x222 (9,19] 1 1 x21 x223 (0,13] 0 1 x31 x32 Is counting process form of a Cox model (coxph with start, stop, cens...

...invoke lli and pass it a list of passes to run, in the manner of opt. For example: > lli -load=llvm/mem_trace_pass/bin/lib/hello.so -hello ./my_bitcode.bc The current implementation of lli (updated from SVN as of three nights ago) doesn't seem to support this. Too see if it would work, I transplanted the required functionality from the opt tool, so the above invocation now works - the pass 'hello' is run by the JIT. This has led to a couple of questions: 1. Did I miss something? As far as I can see, the current JIT implementation has a hardcoded list of pre-defined passes, which de...
