Hi Andrew,

Perhaps this example would help. You can add in spaces to the mtext text
to move the text sideways.

par(mai=c(0.5,0.5,0.5,0.5),oma=c(2,2,2,2))	#mai units are INCHES, oma
units are LINES
plot(runif(50),xlab="xlab",ylab="ylab",bty="l")	#n.b. these labels don't
mtext("First inner x axis label",side=1)
mtext("First inner y axis label",side=2)
mtext("Second inner x axis label",side=3)
mtext("Second inner y axis label",side=4)
mtext("First outer x axis label",side=1,outer=TRUE)
mtext("First outer y axis label",side=2,outer=TRUE)
mtext("Second outer x axis label",side=3,outer=TRUE)
mtext("Second outer y axis label",side=4,outer=TRUE)
