Yes, use something alng these lines:
par(mrfow=c(2,1))
plot(d$a, d$b, col="red")
plot(d$a, d$c, col="red", pch="|")
As both plots use the same data for X you are set. If you need to
force two datasets with different x-ranges into the same range, you
can use the xlim parameter to define the desired range.
