[R] Time-series moving average question

[Bill Poling]

Hello Don, thank you for your response. I appreciate your help.

I am using the forecast package, originally I found it following a forecasting example on bloggers.com

https://www.r-bloggers.com/time-series-analysis-using-r-forecast-package/

And subsequently located the complete pdf https://cran.r-project.org/web/packages/forecast/forecast.pdf

Since I created this practice data using the structure() function I am unsure why there would be NA’s as there are none apparently in the structure?

No worries though, I am going to reach out to the package author.

Cheers.

WHP

My guess would be that if you inspect the output from
ma(dat3[1:28], order=3)
you will find some NAs in it. And then forecast() doesn't like NAs.

But I can't check, because I can't find the ma() and forecast() functions. I assume they come from some package you installed; it would be helpful to say which package.
