My .Rprofile has this (among other items):
lattice.options(default.args = list(page = function(n) {
panel.text(lab = sprintf("%s", date()), x = 0.01, y = 0.01, adj = 0, srt=90)
}))
It prints a "timestamp" along any Lattice plot I make. I think I picked it
several years ago from an R-help posting bt someclever person whose name I am
not remembering at the moment.
