[R-SIG-Mac] 64 bit Mac GUI

[Smith, Edward C]

Simon, I'm following up a post that you responded to online.   
Apologies for the unsolicited email, but I thought you might be able  
to answer a quick question.  I'm running Mac OSX (Leopard) with 4GB  
RAM.  Nevertheless, I was getting the Error: Cannot allocate vector  
of....etc. message running some data and routines on the 32-bit R that  
I installed from CRAN.  I then installed the 64-bit and was able to  
run what I needed without a memory error, BUT, the problem I have now  
is that I can't seem to get a few necessary packages to work in the  
new version.  Specifically, I use routines from the "statnet" and  
"igraph" packages quite a bit.

I see two options.  First, I'd like to have both the 32 and 64 bit  
versions installed on my machine so that I can switch back and forth.   
It seems as soon as I get one installed, the other stops working, and  
vice versa.  The other, better, option is figuring out a way to get  
the packages to work in the 64-bit version.  Is this possible?  I use  
the GUI for both 32 bit and 64 bit (installed the latter per your  
instructions).  Now I seem to be lost completely.

Any help would be much appreciated.

Thanks,
