Actually it may be that the documentation is at fault more than the code. The help page for Plot.Fore says that the first argument is a time series data set and although that seems to suggest that it should be a ts object the code seems to be written assuming a plain numeric vector; therefore, you could do this:
library(zoo) Plot.Fore(coredata(y1), forey1$forecast, start = 1966, end = 1984, frequency = 1) 2009/11/19 Gabor Grothendieck <ggrothendi...@gmail.com>: > Contact the BootPR maintainer regarding a bug in this line of Plot.Fore: > > y1 <- zooreg(x, start, end, frequency) > > where x is a ts object but that may not be used in that context. > as.zooreg is available for converting ts series (and certain other > objects) to zooreg objects. > > 2009/11/19 Ricardo Gonçalves Silva <ricard...@terra.com.br>: >> Hi, >> >> I'm trying to plot the forecasts I generated using the Plot.Fore function of >> the BootPR package. >> But I got an error from zoo: >> >> My data: >> >> Time Series: >> Start = 1 >> End = 18 >> Frequency = 1 >> [1] 38731 38628 39117 92809 71984 31226 58613 72360 107956 92066 >> [11] 95208 99098 95848 120383 110717 105680 98469 101916 >> >> Script: >> >> y1<-ts(y1); >> forey1<-BootBC(y1,p=2,h=3,nboot=5000,type="const+trend",correct="ssf") >> Plot.Fore(y1,forey1$forecast,start=1966,end=1984,frequency=1) >> >> The Error: >> >> Error in zooreg(x, start, end, frequency) : >> "data" : attempt to define illegal zoo object >> >> Any Help? >> >> Thanks >> >> Rick >> [[alternative HTML version deleted]] >> >> ______________________________________________ >> R-help@r-project.org mailing list >> https://stat.ethz.ch/mailman/listinfo/r-help >> PLEASE do read the posting guide http://www.R-project.org/posting-guide.html >> and provide commented, minimal, self-contained, reproducible code. >> > ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
