packcircles 0.3.7 (2024-11-21)

  • Fix: Updated progressive packing vignette example to use ggiraph::girafe() function and fix CRAN warning (thanks to David Gohel).

  • Use the checkmate package to check arguments to functions.

packcircles 0.3.6 (2023-09-05)

  • Fix: Minor change to conform to CRAN package doc conventions.

packcircles 0.3.5 (2022-11-23)

  • Fix: Updated ggiraph dependency to version 0.8.4 to fix error when building one of the vignettes.

packcircles 0.3.4 (2020-12-10)

  • Fix: Minor updates to comply with R extensions convention for using packages listed under 'Suggests'.

packcircles 0.3.3 (2018-09-18)

  • Fix: Minor updates to comply with the planned introduction of STRICT_R_HEADERS in Rcpp.

packcircles 0.3.2 (2018-04-28)

  • Minor change in pads_circle_pack.cpp (graph-based circle packing) to address a CRAN warning.

packcircles 0.3.1 (2018-01-09)

  • Fixed a problem where function circleProgressiveLayout sometimes returned a layout with overlapping circles. Thanks to Jeffrey Lewis for reporting and Peter Menzel for code changes.

packcircles 0.3.0 (2017-11-24)

  • 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.

packcircles 0.2.0 (2017-04-05)

  • 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.
