check whether all elements of a list are in equal in R

Question

I have a list of several vectors. I would like to check whether all vectors in the list are equal. There\'s identical which only works for pairwise comparison.

Answer 1

I woud do:

all.identical <- function(l) all(mapply(identical, head(l, 1), tail(l, -1)))

all.identical(test_true)
# [1] TRUE
all.identical(test_false)
# [1] FALSE
