getLines: Gets the lines shifted according to width

In raredd/Gmisc0: Collection of functions for plotting relations, generating tables, and more.

Description

The lines are the upper and the lower lines that will make up the future polygon that will be used to generate the arrow. These lines are separated from the points by a defined width. The width is perpendicular to the lines angle at that particular point.

Usage

getLines(bp, end_point, width, default.units, align_2_axis = TRUE)

Arguments

bp	Bezier points that define the line. Based upon a bezier grob.
end_point	A list with x & y for the end, only used for the last element's angle.
width	The width as a grid length unit
default.units	The default unit (see the grid package for available units)
align_2_axis	This indicates if the arrows origin should align it to an axis. Which is decided by which axis is the closes one.

Value

A list with left and right elements indicating the two lines
