Dear Sir/Madam,

I am using R version 1.8.1. I am doing following tast:

First generate 100 Gaussion(3,1) numbers, then write the likelihood function 
to estimate the parameters of Gaussian distribution by direct maximizing the 
likelihood function.

My likelihood function is:

After I input above function, the '' >'' turned to be '' + ''. and it did 
not work.

I am looking for the help to solve this tast by writting a likelihood 

Thanks a lot.

Best regards.
