sunspot.year is a built-in R time series dataset which gives the mean yearly numbers of sunspots from 1700 to 1988 rounded to one digit. This data is maintained up until the current date at WDC-SILSO, Royal Observatory of Belgium. We are interested in some descriptive statistics related to the sunspot.year time series. We can access this data directly and convert the time series into a vector by using the assignment x <- as.vector(sunspot.year). (In R use ?sunspot.year for info on...
