R devel - Jul 2005 - translation with Rd.sty, Sweave and tex4th (PR#8016)

Full_Name: Paulo Ribeiro
Version: 2.1-1
OS: Debian Linux
Submission from: (NULL) (200.103.144.24)


I'm using Sweave with tex4th to generate xhtml documents
from documents created using Sweave which include \usepackage{Rd}
in the preamble

However there seems to be a problem with \Link defined in
Rd.sty, since this is also defined in tex4ht.sty

My workaround was to replace the lines with
\newcommand{\Link} by \providecommand{\Link}
in Rd.sty

I'm therefore wondering whether this is the best solution, if there is any
other
and, if so, whether this could be modified in the original Rd.sty shipped with
R.

A possible inconvenient of the suggested above
is that \providecommand seems to be specific to
LaTeX and apparently does not work with TeX.
Another possibility, as suggested by Kurt, would be "emulate"
namespaces
with something of the type \Rd at Link 

with best regards

Why not report this as a bug *in tex4th* that conflicts with R?  LaTeX has 
no namespaces, and unfortunately name conflicts are common.  Doing as you 
suggest and allowing one package to clobber another is much worse.

Nor does \newcommand.  It is part of LaTeX's extra care in finding 
conflicting definitions.

Really a general-purpose package like tex4th should be doing that, not R. 
As many R installations have lots of prebuilt latex files installed, 
changing R's macros can only be done for 3.0.0.
