r - Forcing end of quarter date for as.Date(as.yearqtr()) -


as.yearqtr() zoo package appears use beginning of quarter:

library(zoo) x <- "2015-05-17" x <- as.date(x) x <- as.date(as.yearqtr(x)) x  # [1] "2015-04-01"

how might instead grab end of quarter?

x  # [1] "2015-06-30"

thanks!

use frac = 1 shown:

x <- as.date("2015-05-17") as.date( as.yearqtr(x), frac = 1 )

giving:

[1] "2015-06-30"
