Grouping functions (tapply, by, aggregate) and the *apply family
...'t always obvious, and fall back to a list otherwise. For instance, try to predict the type of output this will produce: sapply(list(1:5, 6:10, matrix(1:4, 2)), function(x) head(x, 1)). What about sapply(list(matrix(1:4, 2), matrix(1:4, 2)), ...)?

What's the difference between emulation and simulation? [duplicate]

Emulation: As opposed to simulation, it does not APPROXIMATE the behaviour of the real system, it COPIES the behaviour of the real system. An emulator may involve har...
