[R] ESS does not recognize installed libraries

[Tae-Hoon Chung]

Hi, all. Something strange happened to my ESS.

I use Mac OS X. When R is used in stand alone mode, it recognizes 
external libraries like "affy", "e1071" etc.
However, when R is invoked through ESS in Emacs, it produces errors 
like:
Error in library(affy) : There is no package called 'affy'
Interestingly, I remember I successfully used these libraries through 
ESS in Emacs before.
I became unable to use these libraries at one moment but I don't recall 
anything strange happened before that.
This kind of strange thing happened sometimes to my R.
In those cases, things restored smoothly when the system is restarted.
However, this time, this trick does not work.

Thanks in advance
