Subject: [Rd] linking to package directories broken in R >= 2.10 beta
Message-ID: <4AD9BB1E.5010408@TU-Dresden.de>

Dear R developers,

some of our packages come with additional programming examples in a 
directory called "/examples" which is created from "/inst/examples".

This directory is linked from the docs (e.g. in inst/doc/index.html):

<dl>
<dt><a href="../examples/">examples</a>:
<dd>Source code of examples
</dl>

Given, that we have a package "foo" this is resolved to:

file:///C:/Programme/R/R-2.9.2/library/foo/examples/

with R <= 2.9.2. With R 2.10 beta (R-beta_2009-10-16_r50118.tar.gz) and 
R-devel (svn rev. 50118) we get:

http://127.0.0.1:26383/library/foo/examples/

This is fine, but in contrast to older versions (<= 2.9.2) no automatic 
index is created for the linked directory, so we now get:

"URL /library/foo/examples/ was not found"

bu linking to *individual files* (e.g. examples/example.R) works as 
expected. We can, of course, add manually maintained index files but I 
would much prefer if a default index would be created for the directory 
if no index.html is found.

I very much enjoy the new help system and would be even more happy if 
that issue could be fixed.

Thomas Petzoldt


PS: A minimal reproducible example (foo_1.0.tar.gz) can be provided by 
mail if required.
