Hi Marc, Why not use the latest release on Windows ?
The callbacks are broken on 2.0.x (and have always been so). It is somewhere in the documentation (http://rpy.sourceforge.net/rpy2/doc/html/overview.html#test-an-installation) but should certainly be also mentioned in the section about callbacks (http://rpy.sourceforge.net/rpy2/doc/html/rinterface.html#i-o-with-the-r-console). I will add a note to that later section. Now to have you going you can either: - start using the version 2.1-dev (callbacks are supposed to work) - use a trick similar to the in RObjectMixin (see below) for the console ouput def __str__(self): if sys.platform == 'win32': tfile = baseNameSpaceEnv["tempfile"]() tmp = baseNameSpaceEnv["file"](tfile, open="w") else: tmp = baseNameSpaceEnv["fifo"]("") baseNameSpaceEnv["sink"](tmp) r.show(self) baseNameSpaceEnv["sink"]() if sys.platform == 'win32': baseNameSpaceEnv["close"](tmp) tmp = baseNameSpaceEnv["file"](tfile, open="r") s = baseNameSpaceEnv["readLines"](tmp) if sys.platform == 'win32': baseNameSpaceEnv["close"](tmp) baseNameSpaceEnv["unlink"](tfile) else: r.close(tmp) s = str.join(os.linesep, s) return s L.
