In R, the IQR() function is used to compute the interquartile range of a given object of numerical values.
The interquartile range of these values is a range where 25% on either side is cut off. Statistically, the interquartile range is the difference between the upper quartile and the lower quartile.
IQR(x, na.rm = FALSE, type = 7)
This function takes the following parameter values:
x: This represents the numeric vector. This is a required parameter.
na.rm: This takes a logical value, TRUE or FALSE, indicating whether missing values be removed or not.
type: This represents an integer selecting one of the many quantile algorithms. This is an oprional parameter.
This method returns the interquartile range of a given object of numerical values.

Line 2: We create an R object, x, containing numerical values from 0 to 10.
Line 5: We implement the IQR() function to determine the interquartile range of the set of numbers and print the result to the console.
