Details
A closer look at faithful$eruptions reveals that these are
heavily rounded times originally in seconds, where multiples of 5 are
more frequent than expected under non-human measurement. For a
“better” version of the eruptions times, see the example below.
There are many versions of this dataset around: Azzalini and Bowman (1990) use a more complete version.
