help with means using tail()
Hi all,
I have 5 series (5 ts objects: rp, igpm, ereal, jurosreal, crescpib), and want to create a vector with the means of the last values of each variable.
What I did was this:
mrp1<-mean(tail(rp,9))
migpm1<-mean(tail(igpm,9))
mereal1<-mean(tail(ereal,9))
mjr1<-mean(tail(jurosreal,9))
mcp1<-mean(tail(crescpib,9))
means=rbind(mrp1,migpm1,mereal1,mjr1,mcp1)
They are monthly series, from 1995.1 to 2011.6.
So what I did was generate the mean of each variable for [2010.10 to 2011.6] (9 months, as I wanted).
But now I want...
