similar to: Creating 2 week intervals (lubridate)

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]

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

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,

I would like to turn this: describe TestClass do before :all do # set some config end after :all do # restore some config end # do a bunch of tests to this end into describe TestClass do with_config_value(X) # do a bunch of tests to this end Basically, I want to include before :all and after :all clauses into a test. However, I do not want this to apply toa ll tests. Thanks in advance.

Hi! I was just wondering what this winedevice.exe actually does. I usually have uTorrent running in Wine all day, and sometimes winedevice.exe starts to use the full CPU. But if I just kill it, everything continues to work just fine... [Question] Toa-Nuva

Hello everybody, maybe someone has also had this issue: I try to copy the root partition "/" to a subdir "/Volumes/System". This is not a cyclic recursion, because "/Volumes/System" is a mounted hard disk partition. So I gave rsync the parameters "-x" for one-file-system, and '--exclude "/Volumes/" ' also: # rsync -ax --showtogo

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

Hello, I know how to increment a date by calendar date: ticker$ldate <- ticker$tdate + days(5) How do I increment it by business days only so that week-ends are not counted? So for example friday november 2 + 5days becomes friday november 9 & not wednesday nov 7. Thanks for your help. -- View this message in context:

#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.

LLVM currently has CMake code to try to detect the various options needed to compile with C++11 support that has been around since prior to the CMake version bump. One of the nicer features that came with the newer required CMake version is that very thing. Rather than try to discern this yourself CMake has the CXX_STANDARD and CXX_STANDARD_REQUIRED target properties. If set appropriately on a

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.

Hi list, I have searched through asterisk command lines but haven't found how to do this: - can I list the phones (callerid or IMSIs?) currently registered ? If I do "dialplan show" that lists the configuration I loaded, e.g [ Context 'sip-local' created by 'pbx_config' ] '2102' => 1. Macro(dialSIP|IMSI1) [pbx_config] '2103'

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
