R语言内置函数(Built-in Functions) R中几乎所有的事情都是通过函数完成的。 下表提供了其它常用的统计函数。 R语言中每个数值运算函数都有na.rm选项,以便在计算前删除缺失值。否则,缺少值的存在将导致结果也是缺失值。统计函数的运算的对象可以是向量也可以是dataframe Function Description mean(x, trim=0, na.rm...

quantile()是R中的一个统计函数,用于计算一组数据的分数或百分比分位数。它提供了四个参数:n是所需分位数的位置,q是从0到1之间的数值,从左到右取值表示从左侧(左闭)的“较低”分到右侧(右闭)的“较高”分的范围,type是类型,可选的参数是“all”(默认为“all”),“lower”(表示从左到右的较低分位点...
