Create a single column gtable

This function stacks a list of grobs into a single column gtable of the given width and heights.

Usage

gtable_col(name, grobs, width = NULL, heights = NULL, z = NULL, vp = NULL)

Arguments

name

a string giving the name of the table. This is used to name the layout viewport

grobs

a single grob or a list of grobs

width

a unit vector giving the width of this column

heights

a unit vector giving the height of each row

z

a numeric vector giving the order in which the grobs should be plotted. Use Inf (the default) to plot above or -Inf below all existing grobs. By default positions are on the integers, giving plenty of room to insert new grobs between existing grobs.

vp

a grid viewport object (or NULL).

Value

A gtable with one column and as many rows as elements in the grobs list.
