R help - Mar 2008 - Question about legend

My original legend is

matplot(c,cbind(ES5,ES75,chisq,t),type ='l',
col=c("brown","red","blue","black"),ylab='power')

legend(5,0.7,paste(c("0.5th ES test","0.75th ES test",
"Chi-square test", "t
test")),col=c("brown","red","blue","black"),lty=1:4,cex=1)

I would like to change "Chi-square" to the greek letter chi^2, how
could I do it in R?

Thanks,

Kate

For the legend= argument use this in place of what you have now:

legend = expression("0.5th ES test","0.75th ES test", chi^2
~ test, "t test")
