Thanks for your reply! Me? Panic?! Never, I have only been working on  
this project for 2.5 years! :)

I was originally in R (the older version) and then I clicked on update  
an option from the Top Tool bar, it brought me to an R page and I  
clicked on update latest version for Mac OS X. I don't think I went to  
the CRAN R installer website and did not know to do so but do not  
remember visiting 'homebrew'.

I just tried launching from the Terminal and it did not work, the same  
default appeared and asked me if I wanted to relaunch again.

Please advise, Jean
