Create a function called my summary that takes a numeric vector as an argument and returns a list. The function should check if the vector is numeric and if it is not, return an error (as understood by R) that the input needs to be numeric. The returned list should include the mean, standard deviation, minimum, and maximum value of the vector. Each element of the list should be given a label.
