BezierCurve-class: Class "BezierCurve": A class to describe a Bezier curve
In Rgraphviz: Provides plotting capabilities for R graph objects

Description Objects from the Class Slots Methods Author(s) See Also Examples

This class is used to represent a Bezier curve in R, which can then be used for other applications, plotted, etc

Objects can be created by calls of the form new("BezierCurve", ...).

cPoints:: Object of class "list": A list of xyPoint objects, representing control points for the curve

cPoints:: Returns the cPoints slot
pointList:: Returns a list of all points having been processed with teh getPoints method of xyPoint
bezierPoints:: Returns a matrix giving x & y points (by column) for the complete Bezier curve
lines:: Draws the Bezier curve
show:: Provides a concise display of information
