I took a look at Hadley's lubridate which seems a very neat package, but i am having a small problem with  concatenating lubridates to build vectors of it. Namely when function c( )  is applied to lubridate seems to change time to a local timezone in this particular case changing the date to previous one.  > d<-ymd('201...

Buas y feliz año y decada nueva, compañeRos, Me estoy encontrando con un problema tonto que no consigo resolver. Explico, tengo un dato que necesito sacar en un documento con codigo on line y no me saca el resultado de consola. dato <- 2272.13 round(lubridate::seconds_to_period(seconds(dato))), 0) En consola me da: "37M 52S" Pero en el documento ```Rmarkdown + Duración total `r round(lubridate::seconds_to_period(seconds(sum(dato))), 0)` ``` Me da: - *Duración total 52* Lo de envolverlo en seconds() lo puse para ver si funciona, y...

...nction in a base package, but they follow the superset principle (i.e. they only extend the API, as explained to me by Herv? Pages). conflicted assumes that packages adhere to the superset principle, which appears to be true in most of the cases that I?ve seen. For example, the lubridate package provides `as.difftime()` and `date()` which extend the behaviour of base functions, and provides S4 generics for the set operators. conflict_scout(c("lubridate", "base")) #> 5 conflicts: #> * `as.difftime`: [lubridate] #&...

It took me some time to realize this annoying behavior was coming from lubridate. Perhaps this behavior is unexpected a result of cursory knowledge of it.... ## The expected behavior > sometimes=c(0,1,2,3)*60*60*24 > as.POSIXct( sometimes, origin='1970-01-01', tz='GMT') [1] "1970-01-01 GMT" "1970-01-02 GMT" "1970-01-03 GMT&quot...

Dear all, I wish to create a POSIXct variable from date and time variables using the ymd_hm function in package lubridate. In some cases data for time is missing, which causes a problem for ymd_hm. I wish to find a smooth way to handle this. # Some example data: x <- data.frame(date = c("2011-09-22", "2011-07-28"), time = c("15:00", NA)) x # paste date and time together to a for...

OK, so the consensus is (1) One cannot make strptime accept ISO8601-compliant zone designators (2) The lubridate package can (3) Or one can hack away with regex. Lubridate it is, then. But I do regard strptime's inability to process ISO8601-compliant zone designators as a bug. On Mon, 6 Nov 2023 at 13:18, jim holtman <jholtman at gmail.com> wrote: > try using 'lubridate' > >...

Hola Miriam, ¿Has probado en cualquier caso?. "lubridate" es capaz de gestionar estas diferencias. Usa la función "dmy()", que entenderá esas pequeñas diferencias con respecto al día.

...invariant? You would expect the wday element to be invariant to the timezone of a date. That is, the same date/time instant of 5th October 2013 in both Australia/Sydney and UTC should be a Saturday (i.e. wday = 6). And indeed that is the case with 1 min past midnight on 5 October 2013: ``` library(lubridate) d_utc <- ymd_hms(20131005000001, tz='UTC') d_local <- ymd_hms(20131005000001, tz='Australia/Sydney') as.POSIXlt(x=d_utc, tz=tz(d_utc))$wday # 6 as.POSIXlt(x=d_local, tz=tz(d_local))$wday # 6 ``` But this isn't always the case. For example, ``` d_utc <- ymd_hms(203...
