The below code will illustrate the action. #creates a vector having … WitrynaThankfully, there’s a way we can work around this. To tell a descriptive statistic function to ignore missing (NA) values, include the argument na.rm = TRUE in the function. This argument explicitly tells the function to ignore NA values.
