example(.) partly broken (since 0.63.3) --> patch (PR#134)
(I don't have time just now to diagnose & fix..)
In R 0.63.3 [both on Solaris and Linux]
> example(outer)
Error: Couldn't find 'outer' example
whereas this worked in 0.63.2.
NON-exhaustive `research' [i.e. small sample out of about 1000]:
o examples that stopped working (in 0.63.3 and did before)
kronecker, outer, vector, Im
o Examples working
.Alias, "%in%", lm, glm, lsfit, unix, Re, ... (most?)
It really is the 'AnIndex' file which is broken,
either because of incorrect syntax in changed *.Rd files
or because the AnIndex building scripts are broken or not robust enough..
My "AnIndex" (i.e. RINSTALL/library/base/help/AnIndex)
has line 482
-----------------------------
glm summaries glm.summaries
-----------------------------
which then is scan()ed as 3 character strings instead of 2, and then
everything following is mixed up......
Other (not necessarily all) such bad lines are
-----------------------------
lm summaries lm.summaries
nrow, ncol nrow
QR Auxiliaries qraux
-----------------------------
However, it seems sufficient [for example() at least]
to patch its source by using scan("..../AnIndex" ..) with sep =
"\t" :

I think one should also apply the following patch
in order to get the HTML indices right.. when AnIndex is allowed to contain
spaces " " in addition to the separating "\t" :
