R: Visualise underlying gtable layout.

gtable_show_grill {lemon}

R Documentation

Visualise underlying gtable layout.

Description

Visualises the table structure or the names of the gtable's components.

Usage

gtable_show_grill(x, plot = TRUE)

gtable_show_names(x, plot = TRUE, rect.gp = gpar(col = "black", fill =
  "white", alpha = 1/4))

Arguments

`x`	A gtable object. If given a ggplot object, it is converted to a gtable object with `ggplotGrob`.
`plot`	Logical. When `TRUE` (default), draws resulting gtable object on a new page.
`rect.gp`	Graphical parameters (`gpar`) for background drop.

Details

These functions are highly similar to gtable_show_layout. gtable_show_grill draws the grid of the underlying table, and places row and column indicies in the margin. gtable_show_names replaces the grobs with a semi-transparent rectangle and the component's name.

Value

Modified gtable object, invisibly.

Examples

library(ggplot2)
library(gtable)
library(grid)

p <- ggplot(mtcars, aes(wt, mpg)) + geom_point()

gtable_show_grill(p)
library(ggplot2)
library(gtable)
library(grid)

p <- ggplot(mtcars, aes(wt, mpg)) + geom_point()

gtable_show_names(p)
