<br>and even reluctance to update to 3.1.0. So some pointers for Mavericks
<br>users
<br>
<br>1) AFAIK no users are going to be worse off using the Snow Leopard build
<br>of 3.1.0 rather than the only (Snow Leopard) build of 3.0.x.
<br>
<br>2) The Mavericks build has support for C++11-using packages (there are
<br>currently less than a handful) and some performance improvements from
<br>its later compilers (and in rare cases these are large).
<br>
<br>3) If you rely on binary packages with are not available for the
<br>Mavericks build, install the Snow Leopard one. Currently that includes
<br>CRAN packages rgdal and rjags and all the BioC packages.
<br>
<br>4) If you install packages from source, you will be most likely better
<br>off with the Mavericks build.
<br>
<br>5) The two builds need different Fortran compilers installed: you can
<br>have both compilers at once. The details are at

As
<br>far as I know a Fortran compiler is only needed if you install packages
<br>from sources.
<br>
<br>Some of the Mavericks binary packages are missing for good reason. The
<br>C++ binary interface for the Xcode 5.x compilers in Mavericks is
<br>completely different, so external software has to be compiled with those
<br>compilers. This affects CRAN packages
<br>
<br>RQuantlib RProtoBuf RVowalWabbit rgdal rjags rzmq
<br>
<br>Most of these can be gotten to work (see the results labelled

<br>from sources. There are packages with badly-written C++ which do not
<br>compile under Mavericks, but as we have been chasing the CRAN
<br>maintainers for a few months there are very few left (the main example
<br>is BioC's package mzR).
<br>
<br>We had expected that by this time Mavericks users would be in a
<br>majority, but it seems the proportion is in the 40s (%). Thus for R
<br>3.1.0 most of the effort has gone into the Snow Leopard build: expect
<br>that to change by R 3.2.0 in a year's time.
