I was just getting around to that section of the script.

I suspect that this is correct and the timing would make sense with my observations here.

Mountain Lion was released on July 25 and I updated shortly thereafter. 

The R 2.15.1 OSX binary is dated June 22, before ML was available, so I would have had that installed under Lion, since I would have updated from 2.15.0 soon after the R OSX binary became available. Thus, 64 bit R would have been the default at that time.

R 2.15.2 was of course released after ML, so that is when the change occurred to 32 bit R. 


Under ML as Berend notes above:

~  uname -r
12.2.0

~  uname -r | grep ^1[012] 
12.2.0


I had sent an initial e-mail to Simon with the information, but he replied from his iPhone that he is away for a couple of weeks sans computer.

In the mean time, I will get in the habit of using 'R64' from the CLI and in ESS.

If there is anything else that is needed, let me know.

Thanks all!

Marc
