Best 64-bit Linux distro for R?

To differentiate the then-different
chips of AMD from Intels Itanium ia64 line, the 'amd64' name was
introduced.  These days ia64 is ancient history and "we're all amd64 users".

By the way, if you decide to go with Ubuntu or Debian, the r-sig-debian list
is there to help.

You will also see the "amd64" architecture referred to by the name
"x86_64". It is yet another name for the same architecture. As far as
the choice of distro is concerned, I've had total success with R on
all the major distros on my 64-bit machine. But I would definitely
give the nod to a Debian-based distro like Ubuntu because of the large
existing base of R packages in the Debian / Ubuntu repositories.
