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)
