Hi
I am using Snow Leopard and I can compile packages (I have all tools
installed) but I am asking myself:
Is there an advantage to using type="source" instead of the binary
install of the packages? For certain packages it makes sense to have
fine grained control to link to certain versions of C libraries
(e.g. rgdal), but is there a general advantage of compiling locally?
There is an advantage if you run multiple versions of R and want to
share a library directory. The CRAN binary versions are tied to the
R.framework installation.
But otherwise
- for the majority of packages (which have no compiled code), there is
almost no advantage in installing from source, but also very little loss
(you need no extra tools).
- The CRAN binaries are built for 3.0.0 I believe, and certainly not
re-built for patch versions. For a very few packages it is advantageous
to use the latest patch version (I am thinking of some issues with
non-Sweave vignettes in recent history, but there have been other issues).
- You might well want to use different external C/C++/Fortran software,
and you may even need to do so or use a different compiler (there are
packages which install with clang but not llvm-gcc and v.v.).
Or is that simply a leftover from my Linux days, that I prefer locally
compiled packages?
Thanks,
Rainer
