treemapify 2.6.1

Minor changes

  • The ‘svglite’ package is now suggested rather than imported, so it is no longer a hard installation dependency; it is only needed to run the package’s pattern-fill visual tests (#66).
  • treemapify()’s help page now documents its return value: the columns of the returned layout data frame, and how rows with zero, negative, or missing area values are handled (#69).

Bug fixes

  • geom_treemap_subgroup_border() (and its subgroup2/subgroup3 variants) now defaults to show.legend = FALSE, so adding a border no longer inflates the legend keys or overrides theme(legend.key.size) (#36, #58).
  • geom_treemap_subgroup_border() now works when an inherited aesthetic such as colour varies within subgroups, rather than erroring (#54, #71).
  • treemapify() now drops rows with a missing area value and issues an informative warning, rather than failing with a cryptic error (#53).
  • treemapify() now keeps tiles within the requested xlim and ylim when a non-default start corner is set (#52).
  • treemapify() now validates the start argument and errors on an unrecognised value, rather than silently treating it as "bottomleft" (#55).
