You can use zoo to do this:
library(zoo)
DA <- c("1991q1", "1993q2")
as.Date(as.yearqtr(DA))

Subject: [R] Convert to as.Date
Hi,
I have an vector object that looks like
DA <- c("1991q1", "1993q2")
(first quarter of 1991 etc) and I want to convert it into a date object
using as.Date(). I did this for montly data but am stumped when it comes
to
dealing with quarterly data and as.Date.
Would anyone be able to help? Would be very grateful for any advice,
sorry
for being such an R-newbie!
Shruthi
