tmap 4.0 (development version)

tmap v4 is a major release and has been rewritten from scratch. It contains a ton of new features. Although we did our best to make changes backwards compatible, some things may not work as expected.

New features

  • tm_vars() is a new function for multivariate scale (#819)

  • New family of functions tm_chart_*() to do charting (See ?tm_chart) (#581)

  • Default styles have been updated and palettes now use the cols4all package for enhanced accessibility (#906)

New syntax

  • tmap now uses visual variables

    • For consistency with ggplot2, tm_polygons() now recognizes the fill argument instead of col.
    • Similarly, border.col is now col.

  • New vignettes available to explain how to upgrade your code to tmap v4.

View mode

  • In view mode, hover is now independent from id (#851).

  • tm_credits() now works in view mode (#806).

  • Popup variables have been revamped.

Deprecated functions and arguments

We introduced messages to make it easier for you to upgrade your code (#961, #928, #854)

Functions

  • tm_scale_bar() -> tm_scalebar()
  • As of version 4.0, tm_scalebar() is used instead of tm_scale_bar() because of the potential confusion with the tm_scale_*() scaling functions (like tm_scale_continuous()).
  • tm_format() and friends are now deprecated (#976).

Arguments

  • projection -> crs (in tm_shape(), tm_grid())

For developers

  • The internal structure of a tmap object is not compatible with tmap v3. Therefore, some tests may fail.

  • tmap exports many functions to make it easier to create an extension (#866) See?tmap_internal.

Other fixes and improvements

  • tmap now requires R 3.6 and above.

  • datasets were reviewed and use a more recent crs. (#967, #665)

  • Usage of the cli package for messages.
