Yes, this worked and I now have R 2.1.0 with both png and jpeg
As an experiment I tried installing the X11 rgl from the mac
installation fails for me with an error on the int* to GLint*
conversion that others have
mentioned as generating only a warning.) The binary rgl does work
up to a point,
e.g. example(rgl) produces the volcano, but mouse movement to rotate the
image acts instead like rgl.clear(), well, this is true for example
(rgl), but for
the point cloud example(rgl.sphere) the mouse is able to rotate the
More theory obviously is needed.....
