Finally, this should work for an array of sigmas. I just realized that the
substitute()-command is not evaluated within a c()-environment :(

mySigma[1] <- 2; mySigma[2] <- 3;
plot(1:10, dnorm(1:10, sd = mySigma[1]), type = 'l') ;
lines(dnorm(1:10,sd = mySigma[2]),lty = 2);
legend(x = "topright", lty = c(1,2),legend = c(substitute(sigma == myS,
list(myS = mySigma[1])),substitute(sigma == myS, list(myS = mySigma[2]))))

Mario.
