Description
Pass in an equal area (not long-lat) projected SpatialPolygonsDataFrame and get
back what you need to plot a Doriling cargogram.
Usage

2
dorling_from_sp(polys, value, n_rescales = 50, n_iter = 50, tol = 1000,
quiet = TRUE)
Arguments
polys
SpatialPolygonsDataFrame
value
values that correspond to the ordered polygons in polys
n_rescales, n_iter, tol
tuning parameters for computing non-overlapping
circle polygon radius values. Tweak only if the defaults do not work well.
quit
if TRUE (default) do not show the scaling iterations
Value
a list with xy coordinate matrix, radius vector, and disc SpatialPolygons
Note
There is a significant limitation in that the polygons have to all be touching
(i.e. this is why the README has an example w/o Alaska and Hawaii). If
neighbors were computed separately or allowed to be passed in, this
could be made more generic. PRs & Issues welcome.
