[R] 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))
