here's the content of a SO deletion by a sanctimonius obstructionist.
I think I've seen an Easter egg or two in some R packages, but I am not able to recall them.
Here are a few from Matlab, and more here, if you want to see some examples of Easter eggs.
Are there any known Easter eggs in R or some of the major packages?
(If justification is really necessary...the reason for asking is simple: some of the Easter eggs for Matlab demonstrate useful functionality and happen to be amusing. I'm not particularly enamored with their "default image" Easter egg, but the examples for simulations (e.g. life and toilet) are actually useful for code and pedagogical purposes. Not all demos need to be dry.)
Update 1: I apologize to any developers offended by this, but my interest is in widely distributed R packages, as it's not that hard to create an Easter egg and drop the package into CRAN. While examples like this "fried eggs" plot and this bunny are a bit amusing, they're not in particularly common packages, as far as I'm aware. However, finding that fried eggs plot did introduce me to the PBSmodelling package which looks rather helpful for other reasons. (RseekAndYouShallFind...some odd stuff.)
Update 2: example(readline) is iffy. It's the closest I found in a scan of the base R code.
