R forecast - How to plot only subset?

Question

I'm fitting a model with the R forecast package like this:

    fit <- auto.arima(df) 
    plot(forecast(fit,h=200))

Which prints the original data frame plus the forecast. This becomes a problem when df is quite big, as it's hard to visualise what the forecast looks like. I would like to be able to select only the last X points from the whole series (original + forecast).

Answer 1

You can include X observations of the original series in your plot with:

plot(forecast(fit, h=200), include = X)

You can see additional documentation with:

?plot.forecast
