as Brian Ripley pointed out, par(mfcol=c(2,2)) or par(mfrow=c(2,2)) will
"fix" your "problem".
the intended use of par(mfg) is to allow you to add extra bits to graphs in
a multiple-graph arrangement. for example, something like ...
par(mfrow=c(2,2))
for (i in 1:4) plot(i)
par(mfg=c(1,2,2,2))
mtext("some text i forgot to add when i first made this graph")
however, this does not excuse R for misbehaving in your example. I will
take a look at what we should do to fix it - thanks for bringing this
problem to our attention !
