You want to start your time series at April 2006 and you want it to have 305 items which means that it starts at April, 2006 and ends in month 103 in 2006. > gnp <- ts(cumsum(1 + round(rnorm(100), 2)), start = c(2006, 4), frequency = > 305) > gnp Time Series: Start = c(2006, 4) End = c(2006, 103) Frequency = 305 [1] 1.08 1.17 1.23 1.89 3.70 4.33 4.45 4.88 6.59 6.71 [11] All this info I got reading documentation. > > Would you please guide me what is the problem with my code?
