Easter Eggs in #Rstats

Yes.

A virtual Easter egg is an intentional hidden message, in-joke, or feature in a work such as a computer program, web page, video game, movie, book, or crossword. The term was coined — according to Warren Robinett — by Atari after they were pointed to the secret message left by Robinett in the game Adventure.^[1] It draws a parallel with the custom of the Easter egg hunt observed in many Western nations as well as the last Russian imperial family’s tradition of giving elaborately jeweled egg-shaped creations by Carl Fabergé which contained hidden surprises

In R.

I like this

just type

example(readLine)

and these two

on 32 bit R type

memory.limit(4096)

and on any version try four question marks

Perhaps the prettiest eggs are the demos in animation package.

But there is magic in asking for help on internal functions in R

Just type-

?.Internal

and you get the sobering thought that you probably are a R Muggle

Call an Internal Function

Description

.Internal performs a call to an internal code which is built in to the R interpreter.

Only true R wizards should even consider using this function, and only R developers can add to the list of internal functions.

Usage

 .Internal(call)

Arguments

call	a call expression

See Also

.Primitive, .External (the nearest equivalent available to users).

I liked that I could see the actual internal functions in svn at http://svn.r-project.org/R/trunk/src/main/names.c

The opening of the internals document floored me.

It must have been a curious year in 2003-4 when the copyright of R was held (briefly it seems) by the R Foundation and also by the R Development Core Team. (which sounds better?)

My contribution

R help discourages for loop

Try ??for or ?for

you go into a loop till you hit escape

If you want more-just write

 .Internal(inspect(ls())) at the end of your  R program.
