[R] unable to access index for repository...

[Steven Yen]

Sorry Gentlemen and all. Now this is becoming a joke (to me). I repeated 
what I did earlier, with and without the option to set repos suggested 
by Duncan. Now it does not work. I wonder whether it is dependent on the 
mirror I chose, but I do not remember the one I chose earlier when it work.

I need your help, gentlemen, as I need to use R-3.0.3 for my task.
