[R-gui] embedding R graphics in Tk widgets

[Felix Andrews]

I have heard about this "figure margins too large" error a few times,
always on Linux.

It sounds like the window is being created too small. I do not know
why. (Does the new playwith window look very small? It is supposed to
be 640 x 500 pixels by default.)

A work-around would be to resize the window to make it larger, then
re-do the playwith() call, or click on the "reload" button in the
playwith window.

Regards,
Felix
