The question is as below:
Exercises
1.The following two calls look the same, but are actually different:
(a <- call("mean", 1:10))
#> mean(1:10)
(b <- call("mean", quote(1:10)))
#> mean(1:10)
identical(a, b)
#> [1] FALSE
What¡¯s the difference? Which one should you prefer?
So, how i can figure out this question?
