?mtext will do what you want.
For example, here is a few codes from Venables and Ripley 2002 "Modern
Applied Statistics with S", Chapter 8.1:
library(MASS)
attach(wtloss)
# alter margin 4; others are default
oldpar <- par(mar = c(5.1, 4.1, 4.1, 4.1))
plot(Days, Weight, type = "p", ylab = "Weight (kg)")
Wt.lbs <- pretty(range(Weight*2.205))
axis(side = 4, at = Wt.lbs/2.205, lab = Wt.lbs, srt = 90)
mtext("Weight (lb)", side = 4, line = 3)
par(oldpar) # restore settings
detach()
Note that you can also get the above codes from
$R_HOME/library/MASS/scripts/ch08.R.
