R help - May 2012 - zoo package; a question on as.yearmon and as.yearqtr

Hello,

   In zoo package, if I would like the time frame to be 1981M01 to 1982M12,
then I code

time_0<-as.yearmon("1981-01")+(0:23)/12


   However, if the time frame of interest becomes 1981M01 to 2011M12, it is
relatively hard to calculate the number of months. Is there any faster way
to do it? Thanks,

miao

Try seq:

seq(as.yearmon("1981-01"), as.yearmon("2011-12"), 1/12)
