[R] Problem with zoo and BootPR packages

[Gabor Grothendieck]

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)
