Thank you, uwe and jeremy. I was actually looking exactly for that! But something still doesn't work: I want to plot a symbol in a legend of a plot, lets say "\sigma = 2". 2 should be the value of a variable. So, when I try mySigma=2;plot(1:10,dnorm(1:10,sd=mySigma),type='l') legend(x="topright",legend=paste(expression(sigma)," = ",mySigma),lty=1) , the sigma is not plotted as a symbol. This version: mySigma=2;plot(1:10,dnorm(1:10,sd=mySigma),type='l') legend(x="topright",legend=expression(paste(sigma," = ",mySigma)),lty=1) gives me a 'real' sigma but the mySigma variable is not evaluated. Any ideas?
Yes:
mySigma <- 2
plot(1:10, dnorm(1:10, sd = mySigma), type='l')
legend(x = "topright", lty = 1,
legend = substitute(sigma == myS, list(myS = mySigma)))

Is there a way to do it the other way round? Particularly, I need some TeX symbols in the legend of an R-plot. This can be done in matlab easily, so I am optimistic with R. Any suggestions for a command or package?
