ggpubr 0.6.0

New features

• New function ggadjust_pvalue() added to adjust p-values produced by geom_pwc() on a ggplot (#522).
• New data added: gene_expression
• Global options: New available package options: ggpubr.null_device, which value should be a function that creates an appropriate null device. These include: cowplot::pdf_null_device, cowplot::png_null_device, cowplot::cairo_null_device and cowplot::agg_null_device. Default is cowplot::pdf_null_device. This is used in function like as_ggplot(), which needs to open a graphics device to render ggplot objects into grid graphics objects. This function is used to open null device for avoiding the display of unnecessary blank page when calling ggarrange() or as_ggplot() (#306 and #158). The default option can be changed using, for example, options(ggpubr.null_device = cowplot::png_null_device).

Major changes

• gadd(): Restoring back random state after setting seed when adding jittered points. To do so, the seed number is just passed to position_jitter() and position_jitterdodge(), which preserve the initial random state ( #177 and #349) .
• ggpubr requires now a version of ggrepel >= 0.9.2.9999, which restores now the initial random state after set.seed(). see slowkow/ggrepel#228
• ggpubr requires now a version of cowplot >= 1.1.1

Minor changes

• ggtexttable(): doc updated with another example; text justification for individual cells/rows/columns (#335).
• ggpie(): setting the default of clip = "off" in coord_polar() so that ggpie() does not crop labels (#429)
• as_ggplot(): using null_device to avoid blank page #306 and #158
• ggarrange(): using null_device to avoid blank page #306 and #158
• Indexing variable in a data frame: using df[[x]] instead of df[, x] to make sure that the result is a vector even if the df is a tibble.
• ggexport(): support added for graphics device svg (#469)
• ggpie() and ggdonutchart() now fully reacts to the option lab.font (#502)
• Replacing deprecated gather_() in both internal (.check_data()) and exported functions (compare_means()) (#513)
• stat_compare_means(): The dot-dot notation (..p.signif..) was deprecated in ggplot2 3.4.0; after_stat(p.signif) should be used; updated so that ..p.signif.. is automatically converted into after_stat() format without warning for bacward compatibility.
• Enable faceting by column names with spaces (#391)
• Licence changed to GPL (>= 2) (#482)
• desc_statby() doc updated to clarify the difference between SD (standard deviation) and SE (standard error) (#492)

• ggexport(): the verbose argument is now considered when specifyed by user (#474)

ggpubr 0.5.0

New features

• New functions stat_anova_test(), stat_kruskal_test(), stat_welch_anova_test(), stat_friedman_test() and geom_pwc() added. These are flexible functions to add p-values onto ggplot with more options. The function geom_pwc() is for adding pairwise comparisons p-values to a ggplot; supportted statistical methods include "wilcox_test", "t_test", "sign_test", "dunn_test", "emmeans_test", "tukey_hsd" and "games_howell_test".
• New functions to convert character vector coordinates into NPC (normalized parent coordinates) and data coordinates: as_npc(), npc_to_data_coordinates() and get_coord().
• Global options:
  • New function ggpubr_options() to display allowed global options in ggpubr
  • New available package options: ggpubr.parse_aes. logical indicating whether to parse or not the aesthetics variables names. Default is TRUE. For example, if you want ggpubr to handle non-standard column names, like A-A, without parsing, then set this option to FALSE using options(ggpubr.parse_aes = FALSE).

Minor changes

• Minimum rstatix version needed is set to 0.7.1
• Minimum ggplot2 version needed is set to 3.4.0
• stat_conf_ellipse: ensure stat returns a data.frame for compatibility with ggplot2 v>=3.4.0

• ggdensity() and gghistogram(): dot-dot notation (..density.., ..count..) replaced by after_stat(density) and after_stat(count), respectively for compatibility with ggplot2 3.4.0.
• create_aes():
  • Default is now to parse its input, which can be an expression (#348). If you want ggpubr to handle non-standard column names (#229), like A-A, without parsing, then set this option to FALSE using options(ggpubr.parse_aes = FALSE).
  • Supports space in column names like "Dimension 1"
  • Unittest added
• Arguments (digits and table.font.size) added to ggsummarystats() for changing the summary table decimal place and text size (#341).
• In stat_pvalue_manual() the argument hide.ns can be either a logical value (TRUE or FALSE) or a character value ("p" or "p.adj" for filtering out non significant by p-value or adjusted p-values).
• Now, the x-axis tick label names correctly align with the corresponding ticks when the rotation angle of the texts is set to 90. This is automatically achieved by setting internally vjust = 0.5 (#301).
• Capital NS. is no longer displayed by stat_compare_means() (#171)
• Unit tests added forggshistogram() to make sure that it works when:
  • using after_stat(),
  • using after_stat() with trailing space inside parentheses.
• Unit tests added forggscatter() to make sure that:
  • it works when there is spaces in variable names
  • it can handle non-standard column names when ggpubr.parse_aes global option is set to FALSE (#229)

• New argument coord.flip added to support adding p-values onto horizontal ggplots (#179). When adding the p-values to a horizontal ggplot (generated using coord_flip()), you need to specify the option coord.flip = TRUE.
• New errorbar functions - median_hilow_() and median_q1q3() - added (@davidlorenz, #209):
  • median_hilow_(): computes the sample median and a selected pair of outer quantiles having equal tail areas. This function is a reformatted version of Hmisc::smedian.hilow(). The confidence limits are computed as follow: lower.limits = (1-ci)/2 percentiles; upper.limits = (1+ci)/2 percentiles. By default (ci = 0.95), the 2.5th and the 97.5th percentiles are used as the lower and the upper confidence limits, respectively. If you want to use the 25th and the 75th percentiles as the confidence limits, then specify ci = 0.5 or use the function median_q1q3().
  • median_q1q3(): computes the sample median and, the 25th and 75th percentiles. Wrapper around the function median_hilow_() using ci = 0.5.
• New function get_breaks() added to easily create breaks for numeric axes. Can be used to increase the number of x and y ticks by specifying the option n. It's also possible to control axis breaks by specifying a step between ticks. For example, if by = 5, a tick mark is shown on every 5 (@Chitanda-Satou, #258).

Major changes

• The following enhancement has been added to ggscatterhist() (@juliechevalier, #176):

  • top: a numeric value specifying the number of top elements to be shown.
• New function theme_classic2() added. Classic theme with axis lines.

Minor changes

• ggboxplot(), ggviolin(), ggdotplot(), ggstripchart(), gghistogram(), ggdensity(), ggecdf() and ggqqplot() can now handle one single numeric vector.

# Example
ggboxplot(iris$Sepal.Length)

• Now, in gghistogram(), when add_density = TRUE, y scale remains = "..count..".
• Now, default theme changed to theme_classic2()
• Default point size and line size set to NULL
