Hi, I was playing with Mandelbrot sets and come up with the following code, I thought I would share:
library(fields) # for tim.colors library(caTools) # for write.gif m = 400 # grid size C = complex( real=rep(seq(-1.8,0.6, length.out=m), each=m ), imag=rep(seq(-1.2,1.2, length.out=m), m ) ) C = matrix(C,m,m) Z = 0 X = array(0, c(m,m,20)) for (k in 1:20) { Z = Z^2+C X[,,k] = exp(-abs(Z)) } image(X[,,k], col=tim.colors(256)) # show final image in R write.gif(X, "Mandelbrot.gif", col=tim.colors(256), delay=100) # drop "Mandelbrot.gif" file from current directory on any web brouser to see the animation Jarek ====================================================\==== Jarek Tuszynski, PhD. o / \ Science Applications International Corporation <\__,| (703) 676-4192 "> \ [EMAIL PROTECTED] ` \ ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
