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. __________________________________________________________________ Mario Maiworm Biological Psychology and Neuropsychology University of Hamburg Von-Melle-Park 11 D-20146 Hamburg Tel.: +49 40 42838 3515 Fax.: +49 40 42838 6591 http://bpn.uni-hamburg.de/Maiworm_e.html http://cinacs.org __________________________________________________________________ >>> -----Ursprüngliche Nachricht----- >>> Von: Uwe Ligges [mailto:[EMAIL PROTECTED] >>> Gesendet: Freitag, 7.
