RE: [R] help for MLE

Hi, when I write the likelihood function as fn-function(x) -50*log(2*pi)-100*log(sigma)-(1/2*(sum((x-mu)/sigma)^2)) then what should I do since it shows that Error in log(sigma) : Object sigma not found. Thanks edward From: Edward Sun Dear Sir/Madam, I am using R version 1.8.1. I am
