Nudge JamPolygon coordinates

Description

Nudge JamPolygon coordinates

Usage

nudge_JamPolygon(
  jp,
  nudge = NULL,
  rotate_degrees = 0,
  center = NULL,
  verbose = FALSE,
  ...
)

Arguments

jp	JamPolygon object
nudge	list whose names match names(jp), containing numeric vector with names "x" and "y". For example: nudge=list(polyname1=c(x=1, y=0))
...	additional arguments are ignored

Details

Polygon coordinates within a JamPolygon object are nudged by name or polygon number, such that all parts of each polygon are adjusted together. For multi-part polygons, and/or polygons with internal holes, all parts are moved the identical amount.
