R on Mac: framework or homebrew?

I used brew install R to install R and I use the most recent version of 
Rstudio. And when I use the "export" in Rstudio, it tells me the following. 
Warning messages:
1: In cairo_pdf(file = "/Users/xinlianzhang/Desktop/Rplot.pdf", width =

Hi 

I am using R at the moment installed from the official installation as a 
framework, buit I also installed it from homebrew. As I am not using the 
Mac GUI (I am using mainly emacs, a little bit RStudio), so from there 
there was no difference. 

So which approach has which advantages? I can think of advantages when 
using homebrew (updates and upgrades of R) and also the framework 
approach (Ease of maintenance). 

I personaly lean towards the homebrew installation (linux background), 
but are there any disadvantages to using the official framework 
installation? 

Any comments? 

Cheers, 

Rainer
