Tag: ggpmisc

This version (0.3.5) adds to geom_table() support for table themes compatible with gridExtra::ttheme_default(). The default table-theme can be changed with function ttheme_set() and several new ttheme constructors are also available as well as support for user defined theme constructors and themes. Changes affect the rendering of tables, and add flexibility to the handling of mapped aesthetics in geom_table(). 

Note: The default theme for tables in version 0.3.5 uses slightly less padding than in previous versions, and this padding is now proportional to the text’s size instead of fixed. This will not break old code but can slightly change how tables look.

The plots below make use of two of the new table theme constructors. The second plot also uses ggplot2’s theme_dark().

Note: If the full flexibility of ‘gridExtra’ and ‘grid’ are needed for a table, the table can be constructed directly with these packages and added as an inset using geom_grob().

This version (0.3.4) adds to stat_poly_eq() the ability to return F-value and P-value in addition to the equation of the polynomial, R², AIC and BIC available in earlier versions of ‘ggpmisc’. The package code and examples have been updated to avoid the use of functions and methods that have been deprecated in recent updates to ‘ggplot2’.

library(ggpmisc) # version >= 0.3.4 !!
ggplot(mtcars, aes(x = wt, y = mpg, colour = factor(cyl))) +
  geom_smooth(method="lm") +
  geom_point() +
  stat_poly_eq(formula = y ~ x,
               aes(label = paste(stat(f.value.label), stat(p.value.label), 
                                 sep = "*`,`~")),
               parse = TRUE,
               label.x.npc = "right") +
  theme_bw()

The code above produces the plot below.
