I have two date objects
X <- c("01-03-1993", "01-05-1997") #Mar 1993 and May 1997
Y <- c("01-02-1995", "01-08-1999") #Feb 1995 and Aug 1999
and a time series object
A <- ts(rnorm(120), freq=12, start=c(1992,8)) #Aug 1992 to Aug 2002
I want to create a binary (0-1) vector B that is of length 1:(A).
B should have value 1 for the time periods *across* my character vectors,
i.e. between Mar 93 ad Feb 95, and also between May-97 and Aug-99, but zero
otherwise.
Would anyone have any ideas on how to do this? I would paste the code I am
trying, but it would confuse rather than clarify (R newbie!). Am getting
really lost in 'for' and 'if' loops, so would really appreciate any help!
Thanks!
Shruthi
