Generates a view on the Mandelbrot set using an underlying C function.

mandelbrot(xlim = c(-2, 2), ylim = c(-2, 2), resolution = 600,
  iterations = 50)

mandelbrot0(xlim = c(-2, 2), ylim = c(-2, 2), resolution = 600,
  iterations = 50)



limits of x axis (real part)


limits of y axis (imaginary part)


either an integer \(n\) for \(n^2\) pixels or a list with x and y components specifying the resolution in each direction (e.g. list(x = 500, y = 500))


maximum number of iterations to evaluate each case


a mandelbrot structure with components: x a vector of the real parts of the x-axis; y the imaginary parts of each number (the y-axis); z a matrix of the number of iterations that \(|z|<2\)


mandelbrot0 is an experimental interface for generating tidy data.frames faster than

Mandelbrot set

In brief, the Mandelbrot set contains the complex numbers where the 0 orbit of the following function remains bounded (\(<2\)): $$f_{z+1} = z^2 + c$$
