Roughly speaking:
matplot(c(0,10), rbind(before, after), type="l", axes=F, xlab="time",
ylab="measurement")
axis(2)
axis(1, c(0,10), c("before","after"))
Should do the job, if I interpret correctly the plot you have in mind.
See help("matplot") : Details, and many pages of help("par") for ways
to modify and decorate the basic plot.
