similar to: POSIXlt$zone and $gmtoff questions

?Hi again, I take advantage of my previous mail to ask you a question for which I was looking for an answer when detected the behaviour I previously told. In the help of DataTimeClasses one can read: "POSIXlt" objects will often have an attribute "tzone", a character vector of length 3 giving the time zone name from the TZ environment variable and the names of the base time

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 <-

Good evening all, This topic is gone into at a bit more length at my related Stack Overflow question here: http://stackoverflow.com/questions/34647674/why-do-as-methods-remove-vector-names-and-is-there-a-way-around-it There are two lingering issues despite the abundant insight received at SO, namely: 1) _Why_ do as methods remove their arguments' names attribute? This is a fact which is

Hola Daniel, si perdona di a responder directamente y no me di cuenta. Ya se donde esta el error, pero queria preguntar si a puede ser que mi R funcione mal o algo porque esta manhana ejecute mi script y funciono perfectamente y ahora volvi a ejecutarlo y me volvio a dar el mismo problema de ayer , despues de reiniciar y demas el tinnR y el R, no se si me vacila o es que tengo algo mal en

I came across the below mis-feature/bug using match with POSIXlt objects (from strptime) in R 2.11.1 (though this appears to be an old issue). > x <- as.POSIXlt(Sys.Date()) > table <- as.POSIXlt(Sys.Date()+0:5) > length(x) [1] 1 > x %in% table # I expect TRUE [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE > match(x, table) # I expect 1 [1] NA NA NA NA NA NA NA NA

Hi all, I'm running into an error when using R CMD check on a package I inherited and I'm now trying to clean up. There are known issues with the Rd files (they definitely need to get updated) resulting in a couple of warnings, but the error occurs before check reaches the Rd files. Below is a snippet of my check.log: * using log directory 'F:/RForgePackages/pkg.Rcheck' * using R

Hi all, I ran into a segfault while playing with dates. $ R --no-init-file ... > library(lubridate); d=as.POSIXlt(floor_date(Sys.time(),"year")); d$zone=NULL; d$zone=""; d Attaching package: ?lubridate? The following object is masked from ?package:base?: date Warning message: package ?lubridate? was built under R version 3.4.0

Hi all, Here's a more minimal version of my earlier bug report (thanks, Joshua Ulrich): d=as.POSIXlt(Sys.time()); d$zone=NULL; d$zone=""; d I got some helpful, if glib, feedback from Joshua that the segfault may be caused by the changing of the order of the list elements in 'd' (representing the "internal structure" of the POSIXlt object). He seems to think that

Thank you for the report. In R-devel, all.equal.POSIXt() by default reports inconsistent time zones. Previously, > x <- Sys.time() > all.equal(x, as.POSIXlt(x, tz = "EST5EDT")) would return TRUE. To ignore the time zone attributes in R-devel, the argument 'check.tzone = FALSE' needs to be used. That said, I can reproduce the 'make check' failure in R-devel on

So, to summarize, the open questions are: (1) Should as.complex(NA_character_) give complex(r=NA_real_, i=0) instead of NA_complex_? (2) Should the first argument in c(NA, x) and c(NA_integer_, x), where typeof(x) == "complex", be promoted to complex(r=NA_real_, i=0) instead of NA_complex_? My opinions: (1) No. The imaginary part of the

So let me try to raise this issue once more, and perhaps be more clear about what I think the issue is.. In my opinion there is now a bug in make check in R-development (tested today with r79361). As I see it, I specify a reasonable TZ environment variable and this leads to make check emitting an error. Best, Kasper On Fri, Oct 2, 2020 at 11:28 AM Kasper Daniel Hansen < kasperdanielhansen

Hi, I have discovered that sample() fails with an uninformative error message when the x argument is a single NA of type double or integer. I can reproduce the problem with the following code: base::sample(NA) # NA is of logical type above base::sample(NA_character_) base::sample(NA_complex_) base::sample(NA_real_) base::sample(NA_integer_) The last two lines throw the following error: Error

Hi Mr Tierney, I have noticed an error message from R 1.12.x's CMD check for a while (apparently prof Ripley completely rewrote CMD check in R 1.12+) e.g.: http://bioconductor.org/checkResults/2.7/bioc-LATEST/snpMatrix/lamb2-checksrc.html ---------------- * checking R code for possible problems ... NOTE Warning: non-unique value when setting 'row.names': ?new? Error in

The return value of Sys.time() today with a timezone of US/Eastern is unchanged between 4.0.3-patched and devel, but on devel the following test fails all.equal(x, as.POSIXlt(x)) with x = Sys.time() This means that devel does not complete make tests (failure on tests/reg-tests-2.R) It is entirely possible that it is an error on my end, I use export TZ="US/Eastern" but I have been
