Adding Latex to text

David Arnold
Hi,

I'd like to add "alpha" in latex code to my image. Any suggestions?

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, "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, "<--beta", col=2)
par(mfrow = c(1, 1))

Perhaps you want to look at

     ?plotmath

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))
