An Analog report is a summary of the information  in your logfiles. If you
combine 2 weeks of summary information, you won't get the same answer that
you would if you analyzed the whole 2 weeks of data.

For example, a Host that visits your site every day, reading a few pages
might not show up in your daily summaries at all, because other,
occassional, visitors would check out more of your site on any given day,
pushing your persistent visitor out of the top 20. But  in an analysis of
all the logs, that daily visitor would show up, because over the two weeks
they would have hit more pages than those one off visitors.

Analog can create "summary" files that preserve most of the information that
you want (see http://analog.cx/docs/faq.html#faq157 ) though you will lose
the links between different parts of the data - you can't use a HOSTEXCLUDE
on a cache file to exclude your own traffic, for instance - you have to use
the HOSTEXCLUDE when you are creating the cache file in the first place, so
you need to decide on what you want in your reports before you create the
cache files. Asking different questions of a cache file than the ones it was
designed to answer is an unreiable process.

You can create the cache file at the same time as you create your .dat file.
When you want to create your monthly or yearly summary, have analog read the
cache files to create a new month.dat or year.dat file - ReportMagic won't
read the cache files directly.
