nSteps {gridBezier}

Calculate Steps for a Bezier Spline

Description

Calculate steps in t for drawing each Bezier curve within a Bezier spline.

Usage

nSteps(n)

Arguments

n

The number of steps (assuming a range of t from 0 to 1).

Details

This function generates a function that can be used as the stepFn argument to grid.Bezier. It will simply generate n values in the range 0 to 1, though if range is also provided, the number of steps is reduced (see the examples below). A minimum of 2 steps will be generated.

Value

BezierGrob produces a "BezierGrob" object.
