mandalar_basic: Create a mandala with algorithm basic

In MandalaR: Building Mandalas from Parametric Equations of Classical Curves

Create a mandala with algorithm basic

Description

Function to create a mandala with the basic method

Usage

mandalar_basic(curve, theta, k, n, raio, a, b)

Arguments

curve	Either a character string or a function returning curve equation evaluated at its first argument. Curves "circle","elipse", "cardioide","limacon", "espiral1", "espiral2", "lemniscata", "deltoide" and "astroide" are recognised, case being ignored.
theta	is a vector length 2 with start angle and end angle
k	is a angle of rotations, k in (0,360) graus
n	is a number of points
raio	is a positive number for the radius of circle
a	is one of the parameters of the curves; for the ellipse is the radius on the x axis
b	is one of the parameters of the curves; for the ellipse is the radius on the y axis

Value

Returns a dataframe with the original points plus the respective rotations of these points.
