I'm still unsure what you mean by "bridge class". The Mac OS X install of R installs the same sort of things as any other Unix variant of R (ignoring the Aqua GUI). You should be able to treat it like any other Unix. The binary distribution puts it all in a Mac OS framework, but that should only be a case adding `/Library/Frameworks/R.framework/Resources/bin` and friends to the normal paths you would search for R in. One would hope that the search paths would be user configurable anyway for those who do not / cannot install R in the default location. What am I missing? What exactly do you need to do differently on Mac OS X?	[reply] [d/l]

The question is, how to know if I'm on Darwin or on Mac OS X using pure Perl! The biggest difference will be only the default installation path to the R binaries. Graciliano M. P. "Creativity is the expression of the liberty".	[reply]

The question is, how to know if I'm on Darwin or on Mac OS X using pure Perl! Just to re-iterate Mac OS X is Darwin, just like Redhat and Slackware are both Linux. You cannot be on a Mac OS X system and not be on Darwin. If you want to know whether your R binaries are in `/Library/Frameworks` then knowing the difference between a Mac OS X box and any other Darwin box isn't going to help you. Frameworks are a Darwin way of bundling stuff together. A non-Mac OS X box running Darwin is also likely to have R in `/Library/Frameworks`. (Equally, a Mac OS X box may not have the R binaries in `/Library/Frameworks` because whoever installed it compiled it from source and chucked it somewhere else.)	[reply] [d/l] [select]
