data()
Access to the data set The
first is the name of the data set, and the content of the data set is introduced later, including all the data types used in R (vectors, matrices, lists, factors, data frames, time series, etc.).
The data can be output by directly inputting the name of the data set: the names of
these data sets are built-in, and it is generally best to avoid duplication when naming variables, otherwise the data set will be replaced.
