In particular, we present methods for computing the Johnston index and the Colomer\u2013Mart\u00ednez measure. Besides, we introduce a new power measure that combines the principles underlying the Johnston index and Colomer\u2013Mart\u00ednez measure as well as a procedure for computing it using generating functions. Finally, we introduce the new R package  and describe its capabilities to compute some power measures by means of generating functions.
