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

** preparing package for lazy loading
** help

Error: argument is of length zero
* removing

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.
