r doesn’t use 0 for an arc index (or any for that matter), whereas topojson does. added +1 to bitflipper function. will this cause problems with any arcs?
pts.poly.arcs.dist now plots histograms and map for arcs. just need to lapply on a list of polygons.
pts.poly.arcs.dist plots boxplots of residuals, and context maps (arcs, polys). next step: move it into rtopojson package.
output residual boxplots and maps not working b/c of os x issue with sourcing .RData
