getFigCtr {plotrix}

Get coordinates in the figure region in user units.

Description

Calculates the coordinates of a proportional point of the figure region in user units.

Usage

 getFigCtr(pos=c(0.5,0.5))

Arguments

pos

The proportion of the figure region to find (see Details).

Details

‘⁠getFigCtr⁠’ reads parameters about the current plot and calculates the vertical and horizontal centers of the figure region by default. This is typically useful for placing a centered title on plots where the left and right margins are very different.

By changing ‘⁠pos⁠’, any proportional points of the figure region can be returned. For example, ‘⁠pos=c(0,0)⁠’ will return the left and bottom coordinates of the figure region.

Value

A two element vector containing the coordinates of the center of the figure region in user units.
