I'm trying to simulate the Brownian motion. The problem is that in my simulation the big particle is overlapped by the other particles. The smaller particles should collide with the big particle.

My code

library(animation)  
ani.options(interval = 0.1, nmax = 100)  
par(mar = rep(0.5, 4))  
BM.circle(n=1000, cex = c(5,rep(0.5,999)), pch = 19, col = c(7,rep(4,999)))`
