g.brownian.motion {animation}R Documentation

Brownian Motion Using Google Visualization API

Description

We can use R to generate random numbers from the Normal distribution and write them into an HTML document, then the Google Visualization gadget ``motionchart'' will prepare the animation for us (a Flash animation with several buttons).

Usage

g.brownian.motion(p = 20, start = 1900, digits = 14, 
    file = "brownian.motion.html", width = 800, height = 600)

Arguments

p number of points
start start "year"; it has no practical meaning in this animation but it's the required by the Google gadget
digits the precision to round the numbers
file the file name
width, height width and height of the animation

Value

NULL. An HTML page will be opened as the side effect.

Note

The number of frames is controlled by ani.options("nmax") as usual.
