positional_tie_line_utils: Locate endpoints of positional tie lines

In aeggers/votevizr: Tools For Vizualizing Election Outcomes

Description

These functions are used to plot positional election results. They locate the points where positional tie lines intersect edges of the ternary diagram.

Usage

from_point_in_xyz_form_v2(pxy, pyx, s)

to_point_in_xyz_form_v2(pxy, pyx, pzx, pzy, s)

point_mat_in_xyz_form_v2(p_vec, s)

ternary_point_mats_from_p_vec_and_s_v2(p_vec, s)

ternary_point_mats_from_p_vec_and_s_v3(p_vec, s)

Arguments

pxy, pyx, pzx, pzy	Second preference shares. e.g. pxy is the proportion of ballots that rank y second, given that they rank x first.
s	The score given to second-ranked candidates in the positional method. s = 0 corresponds to plurality, s=.5 corresponds to Borda count.
p_vec	A vector of second preference shares. If candidates are A, B, and C (plotted at lower left, top, and lower right), then p_vec is (pAB, pAC, pBA, pBC, pCA, pCB).
