Comments on: A serial Connection for R http://biostatmatt.com/archives/112 Wed, 04 Jan 2012 03:50:29 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Matt http://biostatmatt.com/archives/112/comment-page-1#comment-22 Matt Thu, 13 May 2010 14:28:15 +0000 http://biostatmatt.com/?p=112#comment-22 I had originally wanted to write a package to do this sort of thing. The trouble is, the R connections API is not accessible to user extension packages. Hence, any <tt>tty</tt> interface in a package could not provide an R "connection", and not use the associated tools, (i.e. readBin, writeBin). I have discussed this issue on the R-devel mailing list without any real conclusion. Unfortunately, I don't have a Mac, so I'm not of much help with the build toolchain on OS X. But maybe this link would help <a href="http://developer.apple.com/technologies/tools/xcode.html" rel="nofollow">http://developer.apple.com/technologies/tools/xcode.html</a> Mac OS X is certainly compatible. I consulted the Mac OS X documentation while writing this patch, and it is essentially the same as the BSD and Linux documentation.

I would love to have a patched R version to test this out. Too bad it does not work with standard Mac OS X 10.6 Snow Leopard because I can find no easy way to assemble the needed utilities without compromising OSX 10.6 itself. Perhaps some advice would help. Perhaps OS X is not compatible period. I would recommend (hope) that a more standard R package could be developed to implement the tty connection. - AW Very intriguing.
