[R] Dates on Graphics

Thanks for your prompt reply.

I just want to point something out. I already had the date package loaded
and when I tried help(plot.date) I got "Error in help(plot.date) : No
documentation for `plot.date'". There is no mention of it either in the
index of the package (date) in fact it's not mentioned anywhere except in
the source. I don't think this can be called a bug but it would be nice to
be able to find minimal documentation on this function.

This situation bring me to think that it would be nice to have a way to find
information even when you don't know if it exist, some kind of searchable
index. At this time I do this kind of search using the html search
facilities. Is there some other way that one could this?

Before anyone tells me I understand that contributed packages are realized
graciously and it may be wishful thinking to expect package documentation to
be exhaustive, complete and etc... Just may be, there is a way to extract
minimal information directly from the sources and build some sort of
searchable index or database for all packages under the library directory.

Just a thought.
