cowplot 1.0.0 2019-07-11

Breaking changes

In many ways, cowplot now behaves more appropriately and plays nicer with the R environment and other R packages. However, this means that several breaking changes were introduced:

  • The default ggplot2 theme is no longer changed upon loading. You can add theme_set(theme_cowplot()) to your code to restore the old behavior.
  • The package ggplot2 needs to be loaded separately from cowplot, it is not automatically attached.
  • All themes now use parameters font_size and font_family. Previously, theme_nothing() and theme_map() used base_size and base_family.
  • The function cowplot::ggsave() was renamed to cowplot::ggsave2(), so that the ggplot2 version of ggsave() is no longer masked by the cowplot version.

Other breaking changes:

  • The defaults for save_plot() were changed somewhat. This may require adjustment if you have code depending on it.

New features

Minor changes

  • Minor tweaks to various legend layout parameters so that legends look better as the underlying theme font size is changed.
  • Various minor fixes to theme_cowplot() and derived themes.
  • Change background_grid() defaults so they match the new grid themes.
  • Renamed plot_to_gtable() to as_gtable().
  • All functions now understand both spellings of color/colour.
  • get_legend() now returns NULL if there is no legend, instead of raising an error.

cowplot 0.9.4 2019-01-08

  • Fix CRAN check errors

cowplot 0.9.3 2018-07-15

  • Fix regression tests to work with ggplot2 3.0.0

cowplot 0.9.2 2017-12-17

  • Rewritten cowplot::ggsave function that calls ggplot2::ggsave
  • More robust handling of R graphics device weirdness/plots popping up in the wrong places

cowplot 0.9.1 2017-11-16

  • Make examples and vignettes fail gracefully when magick package is not installed

cowplot 0.9.0 2017-11-16

  • Added a theme for maps, theme_map(). Code provided by Spencer Fox, https://github.com/sjfox.
  • Added axis_canvas() function and related functions to make marginal plots and plot annotations simpler
  • Now export the plot_to_gtable function which converts most anything into a gtable for further use with cowplot
  • Added inherit.aes = FALSE to draw functions where needed
  • Added examples to various draw functions
  • Added draw_image() function to draw images onto plots

cowplot 0.8.0 2017-07-30

  • The function plot_grid can now also handle base-R (graphics) plots. Code provided by https://github.com/flying-sheep.
  • More sophisticated plot alignments of complex plots are now possible. Code provided by Spencer Fox, https://github.com/sjfox.
  • Plot labels can now be styled. In particular, they follow the theme settings, e.g. if the theme uses a different font than default. This closes issue #37.
  • The positioning of plot labels in plot_grid can now be controlled with additional position parameters label_x and label_y. This closes issue #32.
  • Problems with elements from globally set themes leaking into the plot-grid background have been fixed. This closes issues #60, #63, #66.

cowplot 0.7.0 2016-10-28

  • This version of cowplot has been prepared for the upcoming release of ggplot2 2.2.0. As a result of this upcoming switch, the function switch_axis_position() has been removed. Alternative axes will be natively supported by ggplot2 2.2.0.
  • As of this version, cowplot requires R >= 3.3.0. This dependency was added because R 3.3 fixes a critical problem with lists of units.

cowplot 0.6.3 2016-09-30

cowplot 0.6.2 2016-04-20

  • Updated plot_grid vignette so the tutorial on aligning plots of different types works again. This stopped working at some point and was removed from 0.6.1.

cowplot 0.6.1 2016-03-06

  • Added new convenience function draw_figure_label() to label figures with labels such as “Figure 1”.
  • Fixes in switch_axis_position() so that rotated axis labels work.
  • Fix missing axis lines in ggplot2 2.1

cowplot 0.6.0 2015-12-19

Major changes:

  • Now requires ggplot2 version 2.0.0 or higher. Use cowplot 0.5.0 with older versions of ggplot2.
  • Because of the dependency on ggplot2 2.0.0, the default design is changed. No more bold face for axis labels
  • Add auto-generation of labels in plot_grid()
  • Add vignettes describing plot annotations and shared legends among plots

cowplot 0.5.0 2015-07-01

Major changes:

  • Fix label positioning in plot_grid() so it is not affected by the scale parameter
  • Add draw_label() function which can draw both text and plotmath expressions
  • Add parameters hjust and vjust to plot_grid() to allow fine-tuning of label position
  • Add annotations underneath plot, via add_sub() function

Other changes:

  • Improve vignettes

cowplot 0.4.0 2015-06-14

Major changes:

  • Added a function switch_axis_position() which can move/copy the x and/or y axis of a plot to the other side
  • plot_grid() can now align graphs
  • plot_grid() can now make grids with varying column widths and row heights

Other changes:

  • Various improvements in the documentation
  • Code has been separated into multiple files for easier maintenance
