[R] root authorization

[Senhua Yu]

Hi,

I am using R 2.0.1 Mac OS X 10.3.5. I was able to authorize R to run system command as root using login and password. But, I forgot to turn this function on before installing Bioconductor, so I terminated the process of the installation. Then, I tried to authorize R to run system command as root, I failed to do that because I saw the locker was not open. I am sure my login and password are correct. How can I recover this function?

Thanks a lot,
Senhua
