Thanks, I'll put this in if nobody else gets there first.

Subject: [Rd] Error in link in Rd file stops package installation
With a pretty recent version of R 2.11.0 (devel,unstable,
svn 50178) on Linux I could not install version 1.5-8 of zoo (the
current on on CRAN):
% R-devel CMD INSTALL -l Rlib3 zoo
* installing *source* package 'zoo' ...
** R
** inst
** preparing package for lazy loading
** help
*** installing help indices
converting help for package 'zoo'
finding HTML links ... done
MATCH html
ORDER html
aggregate.zoo html
as.Date.ts html
as.zoo html
coredata html
frequency html
index html
is.regular html
lag.zoo html
Error: argument is of length zero
* removing
'/a/seafiler01.na.tibco.com/vol/vol2/users/bill/packages/Rlib3/zoo'
The tryCatch calls in the installer code obliterate
most traces of where this 'argument is of length zero'
comes from. If I run the install from a directory containing
the .Rprofile file containing the line
utils::assignInNamespace("tryCatch", function(expr, ...) expr,
ns="base")
then I get:
...
is.regular html
lag.zoo html Error in if
(nzchar(file)) { : argument is of length zero
* removing
'/a/seafiler01.na.tibco.com/vol/vol2/users/bill/packages/Rlib3/zoo'
* restoring previous
'/a/seafiler01.na.tibco.com/vol/vol2/users/bill/packages/Rlib3/zoo'
and I can grep around for 'if (nzchar(file))'. (Redefining q() in
.Rprofile to give a traceback can help in the search also.)
After the attached change to Rd2HTML I get
...
index html
is.regular html
lag.zoo html
Rd warning: ./man/lag.zoo.Rd:54: missing file link 'diff'
make.par.list html
merge.zoo html
...
Line 54 of that help file is
\seealso{\code{\link{zoo}}, \code{\link[stats]{lag}},
\code{\link[stats]{diff}}}
and I think the [stats]{diff} should be [base]{diff}.
The change I made (which isn't quite right but avoids
mysteriously killing the installation for what turns out
to be a minor error) was

A longer range fix would be to print more contextual
information with the error messages from INSTALL.
