R devel - Jun 1997 - R-alpha: write() && quoting && ...

Has anyone had some time to look at the generic write() I posted some
time ago?  I'd appreciate some feedback/comments/suggestions on how to
consistently deal with quoting and name-type attributes ...

On a related matter, Martin indicated that it would be nice to have a
"matrix" class, etc.  Is there any reason for not doing so?  Should
not
do any harm, and would make writing methods for generic functions nicer.

I don't know if this bug has been fixed in a patch I missed, but ...

  line 154 of devPS.c, which currently reads

maxpointsize = 72.0 * ((pageheight>pagewidth)) ? pageheight : pagewidth;

   should read

maxpointsize = 72.0 * ((pageheight>pagewidth) ? pageheight : pagewidth);

  The misplaced parenthesis makes maxpointsize wrong.

  Other comments (things I may get around to fixing when I'm less busy):

   - on quick examination "mkh" appears to have no effect;
   - the components of mgp(x,y,z) appear to get rounded off to integers at
some point, which I don't like (but should at least appear in
documentation if there's a good reason for it); I like to be able to
fine-tune distances ...
   - when using arrows() on a log-scaled plot, you have to use log(x)
coordinates rather than x-coordinates.  This could be intentional (but is
not the way text() works, so I would say it should be made to work the way
text() works).
