Definitely ... he _will_ want to look at ?plotmath, but there is a lot on that page and teh parts that explain the parsing of expressions were not at all clear to me in hte beginning. Some of us find it's better to learn from examples and since he has already constructed a perfectly fine one hten here's my effort at making it "work":
library(UsingR)
BagA = c(rep(10,6),rep(20,5), rep(30,4),rep(40,3),rep(50,2),60,70)
BagA
BagB = c(10, 20,rep(30,2),rep(40,3),rep(50,4),rep(60,5),rep(70,6))
BagB
par(mfrow = c(2, 1))
DOTplot(BagA)
abline(v=60,lwd=2,lty=2,col="red")
text(65,3, expression(alpha*"-->"), col=2)
abline(v=50, lwd=2, lty=2, col="blue")
text(57,5, "p-value------->", col="blue")
DOTplot(BagB)
abline(v=60,lwd=2,lty=2,col="red")
text(55,3, expression("<--"*beta), col=2)
par(mfrow = c(1, 1))
