You can cause some mischief - if you write a package, or distribute a .Rprofile to colleagues, you can hide somewhere in there a

temp <- F

F <- T

T <- temp

and if your colleagues are lazy and use T and F (instead of TRUE and FALSE) fun and very gnarly to debug things are going to happen!

There are way worse things you can do than that! e.g.

`(` <- function(x) { if (is.numeric(x) && runif(1) < 0.1) { x * 1.1 } else { x } }

That is beautiful, thank you very much! That's the kind of "bug" people don't even notice.
