It would be very useful to have a direct way to normalize and standardize features in a data set.

Normalization would subtract the minimum value and divide by the range (difference between maximum and minimum value)

For reals on a Gaussian distribution, standardization would involve subtracting the mean and dividing by the standard deviation.
