getLinesWithArrow: Gets the lines for an arrow

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

Description

The lines are the upper and the lower lines that are later used to generate 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

getLinesWithArrow(bp, arrow, end_points, width, default.units, align_2_axis)

Arguments

bp	Bezier points that define the line. Based upon a bezier grob.
arrow	The arrow list. This should contain a x and y element to indicate the vector in relation to the 0,0 origo. The base element sets the arrow width while the length element gives the length of the arrow.
end_points	The end points of a line. This is a list with a start list(x, y, length) and a end list(x, y, length) as elements.
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
