How to split in R a date range into quarterly basis period? -


i want split monthly date range quarterly basis period. date variable built as.yearmonth:

> data$dates jul. 2014  ago. 2014 sep. 2014 ... ... jun. 2016 jul. 2016 ago. 2016 sep. 2016

how should it? cut function works dates? don't want manually.

lubridate has quarter function. check out:

library(lubridate) x <- ymd(c("2012-03-26", "2012-05-04", "2012-09-23", "2012-12-31")) quarter(x) quarter(x, with_year = true)
