Questions tagged [gtable]

`gtable` is an R package used to facilitate the layout of graphics based on the grid package.

The R package gtable is designed to help construct and manipulate layouts containing graphical elements. The standard grid package in R provides low-level functions to define viewports, and place graphical elements (grobs) at specific locations within the device window. gtable builds upon these functions and provides a higher-level interface, where one can e.g. merge two layouts, add columns, rows, insert graphical elements in a given cell, and change the display order, among other things.

The gtable package is used internally by ggplot2, and can therefore be used to modify the layout of such plots.

Multiple ggplots of different sizes

It's relatively simple using grid.arrange in the gridExtra package to arrange multiple plots in a matrix, but how can you arrange plots (the ones I'm working on are from ggplot2) when some plots are intended to be larger than others? In base, I can…
