Please Use R code to solve this problem:

Create a new function that, given an 'Im'object, returns the top n residuals arranged in descending order according to their largest absolute values (but returns the residuals, not the absolute value of the residuals), where the default value for n is 5. The function should give a clear error message if n is larger than the number of residuals. Demonstrate that your function works by applying it to mtcars.Im
