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
Our new example vector looks exactly as in Example 1, but this time with an NA value at the end. Let’s see what happens when we apply max and min as before: max(x2)# max returns NA# NA The max function returns NA… min(x2)# min also returns NA# NA ...

The behavior of this function template (C++98) is equivalent to: 123 template <class T> const T& min (const T& a, const T& b) { return !(b

在pandas中,apply函数用于对数据帧中的每一列或每一行应用指定的函数。而min函数是一个内置函数,用于返回给定序列的最小值。 对于数据帧中的选择列,可以通过以下步骤进行处理: 1. 首先,...
