R Array Standard Deviation: sd() Function Guide

要计算数组的标准差，可以使用R语言中的sd()函数。该函数用于计算给定数组的标准差。

For example, to calculate the standard deviation of an array x containing a set of values, the following code can be used:

x <- c(1, 2, 3, 4, 5)
standard_deviation <- sd(x)
print(standard_deviation)

In the example above, we defined an array x containing values 1 to 5, calculated its standard deviation using the sd() function, and finally printed the result.
