[R] mfrow is ignored by some plots

I'd ask the plotrix maintainer to fix his code!
radial.plot saves and restores all the par() values, including mfrow and
mfg. When you do par(mfrow=c(2,2)) the plot position is reset to the
bottom right, and the next plot will advance to the top left (but
par(new=TRUE) negates that).
Please restore only the par values you have changed, not all the
no.readonly ones. That values can be set does not make it a good idea to
