Reverse engineering sapply
sapply(list(runif (10), runif (10)),
function(x) c(min = min(x), mean = mean(x), max = max(x)))
Without going straight to the console to run the code, try to reason through which of the following statements are correct and why.
(1) sapply() can't simplify the result that lapply() would return, and thus returns a list of vectors.
(2) This code generates a matrix with 3 rows and 2 columns.
(3) The function that is used inside sapply() is anonymous.
(4) The resulting data structure does not contain any names.
Select the option that lists all correct statements.
