deeptime 2.1.0 (2024-10-25)

This new minor version of deeptime introduces several new features and bug fixes.

New features:

• Added default label color values to all built-in data as a new lab_color column
  • The label colors are either white or black, whichever has better contrast with the background color based on recommendations by the International Telecommunication Union
• get_scale_data() now returns label colors (as above) for Macrostrat timescales
• Varying strip label colors can now be set with the lab_colors argument in facet_wrap_color() and facet_grid_color() (#68)
  • By default, the strip label colors are set to white or black (as above)
• Added facet_nested_color() and facet_nested_wrap_color() to plot nested faceted plots with colored strips (#55)
• get_scale_data() documentation now lists the available Macrostrat timescales (#69)
• get_scale_data() now supports partial matching to Macrostrat timescales (e.g., get_scale_data("mammal") will retrieve the "North American land mammal ages" timescale)

Notable changes:

• The FGDC pattern data added in deeptime 2.0.0 has been moved to a new data R package called deeptimedata to reduce the size of the deeptime package and the footprint of future deeptime updates

Bug fixes:

• Fixed importing some functions from ggplot2 for coord_geo_radial() and coord_geo_polar()

deeptime 2.0.0 (2024-08-19)

deeptime now requires ggplot2 version 3.5.0 or higher.
This new major version of deeptime includes several new features:

• Added FGDC/USGS geologic patterns to internal data (#52)
• Added functions to retrieve and plot FGDC/USGS geologic patterns (#52)
• Added functions to use FGDC/USGS patterns as ggplot2 fills or with the ggpattern package (see new vignette) (#52)
• Added the true_colors option to get_scale_data(), which, when set to FALSE, can be used to retrieve the custom Macrostrat colors that were previously in the built-in datasets (#62)
• Updated built-in timescales to 2023/06 version of GTS
• Added option to coord_geo() to abbreviate interval labels based on only the intervals that are being plotted (#64)
• Added guide_geo() as an alternative to coord_geo(), mostly for use with radial plots (#53)

Bug fixes:

• Fixed the built-in timescale datasets to have true CGMP colors for the Precambrian (#62)

Notable changes:

• The phytools package is no longer required to install deeptime but is required to use the geom_phylomorpho() function
• The geomtextpath package is no longer required to install deeptime but is required to add labels with the coord_geo_polar() or coord_geo_radial() functions
• The gggeo_scale_old() function has been fully deprecated

deeptime 1.1.1 (2024-03-08)

deeptime now requires rlang version 1.1.0 or higher. This patch version includes several bug fixes:

• Fixed several cases where vignette and documentation building and/or unit testing would fail when the Macrostrat API was down
• Fixed coord_geo_polar() and coord_geo_radial() when the r-axis has expansion (#60)
• Improved argument type checking and error handling across the entire package

deeptime 1.1.0 (2024-03-05)

• Added geom_points_range(), a function designed for visualizing temporal occurrence data
• Added facet_grid_color() and facet_wrap_color() for changing strip background colors (#50)
• Added coord_geo_radial(), an enhanced version of coord_geo_polar() (only works with ggplot2 version 3.5.0 and higher) (#56)
• Added family and fontface arguments to coord_geo()

• Fixed the interaction between coord_geo() and ggsave() (#49)
• Fixed size = "auto" when center_end_labels = TRUE in coord_geo()
• Updated several functions to work with ggplot2 version 3.5.0

Notable changes:

• The names for the theme elements that are used for coord_geo_polar() are now prepended with "deeptime." (e.g., deeptime.axis.line.r) (#51)
• ggplot2 version 3.5.0 has broken several edge cases of coord_trans_xy(). See the documentation for more details. This will be fixed in a future deeptime release.
