You can use the 'frame' argument of plot.igraph. Or use the symbols() function.

Hmmm, that is strange. If you just change one dimension, then probably
the other does not change, unless you use the 'asp=FALSE' argument to
plot.igraph. But if you change both, that should work fine.

You mean image quality? PDF is vector graphics, you can scale it any
way you like, the quality will not change.
