New R graphics package targeting HTML 5 canvas element

Hi,

canvas is a new R package implementing a graphics device that emits 
javascript code conforming to the HTML 5 CanvasRenderingContext2D 
interface. Available on CRAN soon, but you can get it here immediately:

If you have access to a beta web browser like Firefox 3.1 or later, you 
can see example plots here:

Clicking on one of the plots will take you to a comparator page where 
the plot is rendered twice, once with the canvas package and once with 
the png(type='cairo') function.

The implementation is almost complete, however there are some parts that 
need work like font metrics and dotted/dashed lines. If anyone is 
interested in helping flesh out the remaining bits, I'd be much obliged.

Best,

Jeff
