Re: [R] What is a expression good for?

You can evaluate it, differentiate it, pick apart its components, use it as a title or legend in a plot, use it as a function body and probably other things too: e <- expression(x+y) eval(e, list(x = 1, y = 2)) # 3 D(e, "x") e[[1]][[1]] # + e[[1]][[2]] # x e[[1]][[3]] # y plot(1:10, main = e)
