In addition to the built-in data sets, many extension packages also have built-in data sets. These data sets are used as cases of built-in functions. These data sets are also loaded when the R package is loaded.
data(package="R包的名字") #可以列出R包中包含的每个数据集
data(package=.packages(all.available = TRUE)) #显示R中所有可用数据集
If you don't want to load the R package, but want to use the dataset in R, use the data function to load it
#data(数据集的名字,package = "数据集所在R包名")
#如：
> help("Nile") #先使用help函数查找相关数据集的信息
> data(Nile,package = "datasets") #不加载R包，使用里面的内置数据集
