I decided to take on the 'proper' solution to calculate the
Mandelbrot set in R, i.e. to do the raw calculations in C and then link
that code with R.
This is very cool. I did a slight tweak to your mandelbrot.R code, so that x can be a list with components x and y. This allows you to keep zooming in using your mouse to click on the plot (one of the incredibly nifty features of such sets).
Using the "tweaked" version below, call the function as you suggested:
image(mandelbrot(), col = c(heat.colors(49), "black"))
Then use locator(2) to define your next view:
image(mandelbrot(locator(2)), col = c(heat.colors(49), "black"))
Click the mouse in the corners of the zoom window, and away you go. Lather. Rinse. Repeat.
Cheers
