"the a <- c(a, b) idiom should usually be replaced by declaring vector a up front the right size (or an upper bound) and assigning to it as a[i] <- b, even if you have to also keep updating i. What is unintuitive is that the idiom often triggers the construction of a whole new copy of a each time."
