I would take the metadata and plot it at the bottom (or top - your 
preference) using mtext. Check out the options oma and the usage of mtext.

        Subject:        [R] How to 'stamp' a plot with meta-data?



Dear R users,

Sometimes, for tracking purposes, I am interested to add to a
plot some metadata such as
* the date it was produced
* filename that stores the plot
* perhaps data sources, author, etc

Ideally, I would like to be able to do this for any kind of plot,
plot(), barplot(), hist(), etc.; and, to be able to produce
plots with or without the metadata by a simple toggle mechanism.

Something like:

# 'Clean' plot
some.plot.func(<args>)  # plot() or barplot() or ...

# Now with metadata
options(metadata=TRUE)  # Or some other toggle mechanism

some.plot.func(<args>)  # Same plot as above, but with wider
# bottom margins that show the
# metadata.

So far I looked in "Introduction to R" and tried to find hints
using help.search() without success.

Is it possilbe to do?
Any suggestions or pointers as to how to do it are appreciated.
Even partial solution in which the plot is set up to accomodate
metadata in the margins, but the data needs to be added manually
after plot()ting will be great.

Thanks in advance,
Itay
