%description
Implements the Single Transferable Vote (STV) electoral system, with clear
explanatory graphics. The core function stv() uses Meek's method, the
purest expression of the simple principles of STV, but which requires
electronic counting. It can handle votes expressing equal preferences for
subsets of the candidates. A function stv.wig() implementing the Weighted
Inclusive Gregory method, as used in Scottish council elections, is also
provided, and with the same options, as described in the manual. The
required vote data format is as an R list: a function pref.data() is
provided to transform some commonly used data formats into this format.
