pads_circle_pack.cpp (graph-based
circle packing) to address a CRAN warning.Feature: Added circleRemoveOverlaps which takes a
set of circles and identifies a subset of non-overlapping circles. The
function can also be set to allow some degree of overlap or require
space between circles. The function uses either a fast heuristic
algorithm (several choices) or linear programming (requires package
lpSolve).
Fix: Replaced use of sprintf with
snprintf in pads_circle_pack.cpp (graph-based
circle packing) to address CRAN warning.
Feature: Added circleProgressiveLayout which
deterministically places each circle in turn such that it is externally
tangent to two previously placed circles while avoiding
overlaps.
Feature: Replaced circleLayout with a new function
circleRepelLayout. The original function is retained for
backwards compatibility but is deprecated and will be removed in a
future release. Important note: the new function
accepts circles sizes as either areas or radii. The default is area,
unlike circleLayout which assumed sizes were radii. The
type of size value can be specified using the sizetype
argument.
Feature: Replaced circlePlotData with a new function
circleLayoutVertices. The original function is retained for
backwards compatibility but is deprecated and will be removed in a
future release. The new function has a sizetype argument to
specify whether the input circle sizes are areas or radii. By default,
radius is assumed as this matches the output of the layout functions but
I realize it’s a bit confusing.
Internal: Removed gridExtra from suggested
packages.
Internal: Added ggiraph (used for
vignette).
Docs: Re-wrote the introductory vignette and added a new vignette
for circleProgressiveLayout.
Docs: Edited function docs and examples.
Internal: Added file for native routine registration as now required by CRAN.
