> I wanted to simulate the Matlab DISPLAY function for some time now. After seeing a recent proposal by Gabor Grothendieck I came up with the following solution, display <- function(...) { my_names <- lapply(substitute(placeholderFunction(...))[-1], deparse) for (my in my_names) cat(my, "=", eval(parse(text=my)), "\n", sep=" ") } that works about as good as I would have hoped: > a <- 1; b <- a + 1 > display(a, b, sin(1)) a = 1 b = 2 sin(1) = 0.841471 My questions:...
