This function converts a gtable, as produced by ggplot2::ggplotGrob() and makes it ready to be added to a patchwork. In contrast to passing the gtable to wrap_elements(), wrap_ggplot_grob() ensures proper alignment as expected. On the other hand major restructuring of the gtable will result in an object that doesn't work properly with wrap_ggplot_grob().

wrap_ggplot_grob(x)

Arguments

x

A gtable as produced by ggplot2::ggplotGrob()

Value

A table_patch object to be added to a patchwork

Examples

library(grid) library(gtable) library(ggplot2) p1 <- ggplot(mtcars) + geom_point(aes(mpg, disp)) + ggtitle('disp and mpg seems connected') p2 <- ggplot(mtcars) + geom_boxplot(aes(gear, disp, group = gear)) # Convert p2 so we can add new stuff to it p2_table <- ggplotGrob(p2) stamp <- textGrob('TOP SECRET', rot = 35, gp = gpar(fontsize = 72, fontface = 'bold') ) p2_table <- gtable_add_grob(p2_table, stamp, t = 1, l = 1, b = nrow(p2_table), r = ncol(p2_table) ) # Adding it directly will loose alignment p1 + p2_table
# Use wrap_ggplot_grob to keep alignment p1 + wrap_ggplot_grob(p2_table)
