similar to: lubridate does not install on FreeBSD any more

After building and installing R-devel from 21/07/2011 on FreeBSD 9.0-CURRENT (amd64), starting R gives the following warning: [..snip..] Beim Start - Warnmeldung: package 'datasets' in options("defaultPackages") was not found This happens with all versions after 14/07/2011. I think it is related to NEWS Sat, 16 Jul 2011 CHANGES IN R-devel PACKAGE INSTALLATION Packages without

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('20111231') > d [1] "2011-12-31 UTC" > c(d) [1]

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

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

Hi all, This summer I've been working with a grad student to bring more of the date time classes from JODA (http://joda-time.sourceforge.net/) into R. To make these work seamlessly with existing date time objects, we need to patch +.POSIXt. (The ruby community uses the term monkey-patching for this sort of ill-advised, by sometimes necessary, internal hackery, hence the title.) The problem is

Hiya, maybe there is a native R function for this and if so please let me know! I have 2 data.frames with start and end dates, they read in as strings and I am converting to POSIXct. How can I check for overlap? The end result ideally will be a single data.frame containing all the columns of the other two with rows where there were date overlaps.

#lubridate lubridate makes it easier to work with dates and times by providing functions to identify and parse date-time data, extract and modify components of a date-time (years, months, days, hours, minutes, and seconds), perform accurate math on date-times, handle time zones and Daylight Savings Time. lubridate has a consistent, memorable syntax that makes working with dates less frustrating.

Please find below the package announcement for the R package lubridate available from cran. Thank you, Garrett Grolemund Rice University ##lubridate Date-time data can be frustrating to work with in R. R commands for date-times are generally unintuitive and change depending on the type of date-time object being used. Moreover, the methods we use with date-times must be robust to time zones,

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" "1970-01-04

Version 2.2 of the lubridate package is now available. lubridate makes it easier to work with date-time data. For example, it provides: * simple functions to extract and modify components of a date-time, such as years, months, days, hours, minutes, and seconds: year(), month(), day(), ... * quick and easy functions to parse date-times: ymd(), dmy(), mdy(), ... * helper functions for handling

Hello, is there any function in the package snow to check for a really running cluster? The function checkCluster only checks the variable cl. And the variable is still available after stopping the cluster! ( a simple solution would be deleting the cluster variable cl in the function stopCluster) > library(snow) > cl <- makeCluster(5) 5 slaves are spawned successfully. 0

Dear community, I am looking for a possibility to draw 'regression lines' instead of 'smooth' lines in grouped xyplots. The following code should give you a small example of the data structure. library(lattice) data(Gcsemv, package = "mlmRev") # Creates artificial grouping variable ... Gcsemv$Groups <- ifelse(as.numeric(as.character(Gcsemv$school))>65000,

Dear list, this may not be related to R but rather to my OS, but I do not understand the issue of compiling R packages deeply enough to figure out the exact cause of the problem. I am trying to install a R package from source as it is not yet available under Cran (Rssa, downloaded here: https://github.com/asl/rssa). Running sudo R CMD INSTALL asl-rssa-6f458e4.tar.gz from the console

Dear list, in R under wheezy the following error occurs: > library(cairoDevice) > Cairo() Error in Cairo() : Graphics API version mismatch It seems to be Debian-specific, as I tried the same under OpenSUSE 11.3 and it worked. I tried installing cairoDevice via `apt-get install r-cran-cairodevice' and with `install.packages("cairoDevice")' in R (without any

Dear Developers, I'm updating my R installation via svn (currently: Revision 44626).

Dear userRs, "playing around" with combinations of replicate() and random number generating functions inside a self-defined "wrapper" function I encounterd a puzzling behaviour. The following are intentionally simple (and rather nonsense-) examples to isolate the relevant aspects. Please, note the seemingly "inconsistent" behaviour for the second call of
