ggtexttable() (#125, #129 and #283):
tab_cell_crossout(): cross out a table cell.tab_ncol(), tab_nrow(): returns, respectively, the number of columns and rows in a ggtexttable.tab_add_hline(): Creates horizontal lines or separators at the top or the bottom side of a given specified row.tab_add_vline(): Creates vertical lines or separators at the right or the left side of a given specified column.tab_add_border(), tbody_add_border(), thead_add_border(): Add borders to table; tbody is for table body and thead is for table head.tab_add_title() and tab_add_footnote() to add titles and footnotes (#243).create_aes() added to create aes mapping from a list. Makes programming easy with ggplot2 (#229).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.median_hilow_() and median_q1q3() - added ([@davidlorenz, #209](https://github.com/kassambara/ggpubr/issues/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.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](https://github.com/kassambara/ggpubr/issues/258)).ggscatterhist() ([@juliechevalier, #176](https://github.com/kassambara/ggpubr/issues/176)):
