similar to: lubridate:ymd_hm and coercion of class POSIXct. Smooth way to restore the date format.

Hi all, I have multiple datasets of time series data taken from GPS collars. The collars are supposed to take a fix every hour on the half hour, i.e., 0:30, 1:30, 2:30...23:30, (because it sometimes takes longer for the collars to acquire a location the minute of these locations vary from 30-34) but because of a software glitch in the collars, at random times the collars start taking multiple

I am trying to convert an array from numeric values back to date and time format. The code I have used is as follows; for (i in 0:(length(DateTime3)-1)) { DateTime3[i] <- (strptime(start, "%m/%d/%Y %H:%M")+ i*interval) where start <- [1] "1/1/1981 00:00" However the created array (DateTime3) contains [1,] 347156400 347157600 347158800 347160000 347161200 347162400

Hello Forum, I have a problem with the strptime function. With the ''data1'' dataset below it works fine, but with the ''data2'' dataset something goes wrong (see final line below). Both data1 and data2 are in exactly the same original format, the only difference is that they span different dates. Please help, since it is driving me nuts! Many thanks. Best

Dear R-bug-people I have encountered a problem with "unsplit", which I believe may be caused by a bug in the function. However, unexpericend with bug-reports I apologise if this is barely a user problem rather than a problem within R. The problem occurs if an object is split by several grouping factors with levels not occuring in the data, and using drop = TRUE. This may appear as

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,

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

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

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]

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:
