Align boxes

Description

Aligns a set of boxGrob/boxPropGrob according to the first positional argument.

Usage

alignVertical(reference, ..., .position = c("center", "top", "bottom"))

alignHorizontal(
  reference,
  ...,
  .position = c("center", "left", "right"),
  .sub_position = c("none", "left", "right")
)

Arguments

reference	A boxGrob/boxPropGrob/coords object or a unit or a numerical value that can be converted into a unit of npc type.
...	A set of boxes.
.position	How to align the boxes, differs slightly for vertical and horizontal alignment see the accepted arguments
.sub_position	When the box is a boxPropGrob it not only has the general .positions but also left and right which can be viewed as separate boxes that have simply been merged.

Value

list with the boxes that are to be aligned
