Well, I am simply following as much as my, probably limited,
understanding allows. I am using a stock Debian install, r-base and
other packages from debian, and extra packages from CRAN. My package
follows, as far as I can tell, the manual. If I am doing something else
I am not conscious of it.
Ah, but that is not what you actually said (an example of the lack of
clarity).
At least that´s what I tried to do.
I still don't know if you are imagining that there might be a problem that
you want to write a package to avoid, or that you have a current problem.
I´ll rather use my imagination for something else. This is a problem
with my own package, that in fact passes R CMD check.
If the latter, please start again with the full details: which packages,
the commands you used to install them, what happens and what the links in
the html file concerned are.
Here we go: The package concerned is my own, which passes check fine. I
include \code{\link{plot.default}} in a help page. After R CMD INSTALL
this page gets installed in
/usr/local/lib/R/site-library/mypackage/html/page.html
and when clicking on the plot.default link, it points to
/usr/local/lib/R/site-library/graphics/html/plotdefault.html
instead of
/usr/lib/R/library/graphics/html/plotdefault.html
where in fact lives.
Both locations appear with .libPaths().
Any other information that can be of help?
Cheers,

I asked for `what the links in the html file concerned are', so, yes, the
information I asked for would help.
It should be a relative link like
codea href=../../stats/html/optim.htmloptim/a/code
Under Linux, all HTML links are created to the per-session directory and
not to the original locations.
I think you are expecting to be able to open the installed html file
directly in a browser and get the links to work. That's what you have not
told us you were doing, and you won't find it documented anywhere in the R
documentation. (Ironically, it does work under Windows with a separate
library tree.)
To view R HTML documentation you need to use help.start(). (Otherwise
help(foo, htmlhelp=TRUE) will warn about possible incorrect links.)
Try the documented way
Start R
help.start()
help(page)
and the links will be correct, I am pretty sure.

Maybe a mention of the mechanism on the administration manual could be of help? I think you are expecting to be able to open the installed html file directly in a browser and get the links to work. Indeed. and you won't find it documented anywhere in the R (Ironically, it does work under Windows with a separate library tree.) That irony was puzzling me, of course. That was the reason I mentioned a non-Debian install. and the links will be correct, I am pretty sure. Not all of them. help-links.sh has problems with the permission of, among others /usr/lib/R/doc/html/R.css. But this might be, this time, a debian installation problem.

[Rd] regex to match word boundaries
Can someone verify whether or not this is a bug. When I substitute all occurrence of \\B with X R seems to correctly place an X at all non-word boundaries (whether or not I specify perl) but \\b does not seem to act on all complement positions: gsub(\\b, X, abc def) # nothing done [1] abc def gsub(\\B, X, abc def) # as expected, I think [1] aXbXc dXeXf gsub(\\b, X, abc def, perl = TRUE) # not as expected [1] abc Xdef gsub(\\B, X, abc def, perl = TRUE) # as expected [1] aXbXc dXeXf R.version.string # Windows 2000 [1] R version 2.0.1, 2004-11-27 __ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

Just to confirm: 1) I get the same on a Linux version 2) the real perl does behave differently and as you (and I) would have expected: $ echo 'abc def'| perl -pe 's/\b/X/g' XabcX XdefX $ echo 'abc def'| perl -pe 's/\B/X/g' aXbXc dXeXf Also, from what I see, \b should behave the same independently of perl = TRUE or FALSE. -- Martin __ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
