Hello all, Could someone help me with the time zones in understandable & practical way? I got completely stucked with this. Have googled for a while and read the manuals, but without solutions... ------------------------------------------------------------------- When data imported from Excel 2007 into R (2.13) all time variables, depending on date (summer or winter) get (un-asked for

Hello, I'm new to R and I'm trying to define new quite simple variable but I'm struggling with R syntax (when coming to dates) for a while and still getting <errors> on it. I would be very grateful if someone could help me with this, to be able to move on. I have the following variables: - Transplant.date - Faildate - Death.date The new variable Time should do the

dear R-team I need to find the min, max values for each patient from dataset and keep the output of it as a dataframe with the following columns - Patient nr - Region (remains same per patient) - Min score - Max score Patient Region Score Time 1 1 X 19 28 2 1 X 20 126 3 1 X 22 100 4 1 X 25 191 5 2 Y 12 1

Dear List, After including cluster() option the coxreg (from eha package) produces results slightly different than that of coxph (from survival) in the following time-dependent treatment effect calculation (example is used just to make the point). Will appreciate any explaination / comment. cheers, Ehsan ############################ require(survival) require(eha) data(heart) # create weights

From POSIXct to numeric and back with time zone I am running regressions on data which has time series with different time resolution. Some data has hourly resolution, while most has either daily or weekly resolution. Aggregation is used to make the hourly data daily, while liner interpolation is used to find daily data from the weekly time series. This data manipulation requires some careful

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

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)

Dear all, I have just detected what seems a minor inconsistence with data types. If one unlists a POSIXlt time with GMT zone gets a numeric vector, since the POSIXlt list has no `zone` element, while if one unlists a POSIXlt time with a non GMT zone (also non specifying tz if the Sys.timezone is not GMT) gets a character vector due to including the `zone` element. > x <-

I want to essentially transplant my existing Asterisk server to a new machine, and take the old sever out of service. Assuming I install Asterisk on the new machine, does anyone know what files I would have to copy over? What comes to mind are the *.conf files in /etc/asterisk, as well as the voicemail audio files. Anything else? -------------- next part -------------- An HTML attachment was

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 random sites each of two types

It is not completely clear to me how time zones work with POSIXlt objects. For POSIXct, I can understand what happens: time is always stored in GMT, the `tzone` attribute only affects how the times are displayed. All computations etc. are done in GMT. POSIXlt objects have both a `tzone` attribute and a `zone` field. It seems that the `zone` field is largely ignored. It only seems to be used

POSIXt vectors do not support different time zones element-to-element. If you want to keep track of timezones per element, you have to create a vector of timestamps (I would recommend POSIXct using UTC) and a parallel vector of timezone strings. How you manipulate these depends on your use cases, but from R's perspective you will have to manipulate them element-by-element. I complained about

Hi, I'm trying to transplant samba 3.2 to my mips board. I did it but smbd is too big, about 8MB, I decided to reduce the code size. I just want the file share/display funcs between my box and windows PC. The first function I want to drop is network printer. So is there a specific option to drop all printer code? It seems to take quite a lot of time to let me comment out things I

Dear List, I have a theoretical question related to epidemiological data analysis: If the treatment status (tx = 0,1) changes over time for the patients in 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

I've been trying to build R 3.3.1 inside of a Nix environment on a Ubuntu 16.04 machine. It builds, but then it fails a regression test related to time zones, and I hope that someone could help me debug the problem. The failing test is in tests/reg-tests-rc.R (https://github.com/wch/r-source/blob/c3fe9cd4/tests/reg-tests-1c.R#L1577-L1587): ## format.POSIXlt() of Jan.1 if 1941 or '42 is

Sys.setenv(TZ = "GMT") will set the local time zone to GMT so there would only be one time zone regardless of whether local or GMT were used.

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!"

Evidently handling timezones per element was considered to be too impractically slow to be a standard feature. This is where it is unclear to me what the purpose is of the
