Aligns a set of boxGrob
/boxPropGrob
according to the first positional argument.
alignVertical(reference, ..., .position = c("center", "top", "bottom"))alignHorizontal(
reference,
...,
.position = c("center", "left", "right"),
.sub_position = c("none", "left", "right")
)
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.
How to align the boxes, differs slightly for vertical and horizontal alignment see the accepted arguments
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.
