Test if object is an n-dimensional measure tibble
Examples
# Create a 2D measure tibble
mt <- new_measure_nd_tbl(
location_1 = 1:10,
location_2 = rep(1:2, each = 5),
value = rnorm(10)
)
is_measure_nd_tbl(mt) # TRUE
#> [1] TRUE
# Regular tibbles are not measure_nd_tbl
is_measure_nd_tbl(tibble::tibble(x = 1:5)) # FALSE
#> [1] FALSE
