is_range()
tests whether or not an Excel formula is a range.
A formula like A1
is a range, whereas a formula like MAX(A1,2)
is not.
Formulas are not evaluated, so it returns FALSE
for formulas that would
eventually resolve to arrange (e.g. INDEX(A1:A10,2)
) but that are not
immediately a range.

x <- c("A1", "Sheet1!A1", "[0]Sheet1!A1", "A1,A2", "A:A 3:3", "MAX(A1,2)")
