hi there! i am desperately in need for help. i have read in data: qthm=read.csv("qthm.csv",sep=";",header=TRUE) then created time series ie m2=ts(log(qthm$m2), start=c(1959, 1), frequency=4) transformed these time series in zoo variables qthmz=merge.zoo(diff(mbase),diff(m2),diff(cpi),diff(rgdp)) Now I want to analyse these date, but for different periods. How to I create new time series or zoo variables with a shorter time span ie from 1959.00 to 1979.75 only? I have already read through several possibilities but nothing seems to work well for my case, what do you recommend? kind regards, phillen -- View this message in context: http://r.789695.n4.nabble.com/changing-time-span-tp4413672p4413672.html Sent from the R help mailing list archive at Nabble.com.
