M4 Documentation:

This step demonstrates a simple method of replacing nominal values by numeric ones. The new attribute created here uses the numbers 1,2 and 3 as if they were still nominal, but any succeeding step can simply interpret them as numeric. Note that this method may introduce an order into the values which may not be intended. In this example here the order can be justified because ascending numbers are given to stronger wind conditions.
