[R] [External] Re: code for drawing the R logo

[Barry Rowlingson]

The SVG isn't that complex, it defines two colour gradients (one for the R
and one for the ring) and then draws each one using a series of cubic
bezier curves and lines

These are in <path> tags in the SVG which look like this:

M361.453,485.937 C162.329,485.937 0.906,377.828 0.906,244.469
C0.906,111....etc

 M is "move to" and then "C" defines a curve, "L" defines a straight line I
don't think any other path items are used.

There's two paths, each being two parts because both the R and the ring
have holes in them.

 If you want to draw this from scratch in R code, first write (or find)
code to draw cubic bezier curves as per the SVG spec, then extract the
coordinates from the path attributes in the SVG then make polygons and
shade them using the colour gradients at the start of the SVG...
