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
