R sequence of dates with lubridate
lubridate, r
Solution
`ymd` is a wrapper to parse date strings and returns a `POSIXct` object.
You simply need to use standard terminology described in `?seq.POSIXt` (not `lubridate`) to define weeks
seq(ymd('2012-04-07'),ymd('2013-03-22'), by = '1 week')
seq(ymd('2012-04-07'),ymd('2013-03-22'), by = 'weeks')
will works
as will
seq(ymd('2012-04-07'),ymd('2013-03-22'), by = '2 week')
You could coerce the `lubridate` `Period` class object to a `difftime`, but that seems rather unnecessary
seq(ymd('2012-04-07'),ymd('2013-03-22'), by = as.difftime(weeks(1)))
Problem
Hi I'm trying to get a sequence of dates with lubridate This doesn't work ``` seq(ymd('2012-04-07'),ymd('2013-03-22'),by=week(1)) ``` the base command ``` seq(as.Date('2012-04-7'),as.Date('2013-03-22'),'weeks') ``` does, but I'd like to know if there is an elegant way to do this with lubridate. EDIT Please ignore : solved myself so leaving up for posterity only. Happy to have this deleted if necessary. ``` seq(ymd('2012-04-07'),ymd('2013-03-22'),by='weeks') ``` Does the trick
