I use this little function for adding a datestamp manually.
runstamp <- function (adj = 1, cex = 0.75, line = 4)
mtext(format(Sys.time()), side = 1, adj = adj, cex = cex, line = line)Since the default lower margin is 5.1, line = 4 works pretty well. You can, of course, put any other information you want in there. But to have it all automated looks to me like a major task. I wouldn't get my hopes up.

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
