fixed problems by creating new ab.arcs variable which stores info about arcs with 2 sides of observations
improved t-test to do t.test(A near X,A not near X) rather than (A near X,A) —see mark’s email dated dec 13th, 2013
boundaries based on new t-tests in qgis
copying from arcsummary to here for source()’ing
the ab.arcs.2sided doesn’t seem to be ruling out all arcs without observations. for example, in the current abt.poly.idx.selection, row 69 referes to polygon 13, which has 0 houses.
fixed tw.sd (two sided) selection for enough observations. previously, was made with correspondence to arcs, now made w/correspondence to poly/arc index.
updated shapefiles to reflect new code in SignificantArcs
fixed two sided selection-see commit 2 previous
