R Max and Min

This lesson is part of R · All levels

Summary

This lesson discusses the search for the lowest and highest extreme values in a dataset using the functions min(), max(), which are often used in preprocessing statistical data. In addition, the functions which.min() and which.max() were introduced to track the row number or position index where such extreme values occur.

Key points

The 'min()' function returns the smallest numerical value in a data set
The 'max()' function returns the largest numerical value in a data set
The 'which.min() ' function returns the index number of the element with the minimum value
The 'which.max() ' function returns the index number of the maximum value element
Use 'na.rm = TRUE' if the data potentially contains missing values
