The lesson says quantile() is a base R function, but when I looked up the documentation on the following site: https://www.rdocumentation.org/packages/stats/versions/3.6.2/topics/quantile, it says quantile() is part of the stats package. Which is right?

did you mean quartiles? vs quantiles


I think they mean that quantile() is automatically loaded into R, and that you don’t need to manually load the package to be able to use the function (assuming you have a standard R setup of course).

You are indeed right that there is a (historical?) difference between the base and stats package, but for the common user there’s no real difference, and I think that’s an imprecision/simplification on their side, a simplification especially for people that come from programming in Python and other languages with a similar syntax, where everything that is not a basic function has to be imported.

All the best,
