Get the number of dimensions of a measurement

Returns the dimensionality of a measurement object. For 1D measurements (measure_tbl), returns 1. For n-dimensional measurements (measure_nd_tbl), returns the number of location dimensions.

Usage

measure_ndim(x)

Arguments

x

A measure_tbl, measure_nd_tbl, measure_list, or measure_nd_list object.

Value

Integer indicating the number of dimensions.

Examples

# 1D measurement
m1d <- new_measure_tbl(location = 1:10, value = rnorm(10))
measure_ndim(m1d)  # 1
#> [1] 1

# 2D measurement
m2d <- new_measure_nd_tbl(
  location_1 = rep(1:5, each = 3),
  location_2 = rep(1:3, times = 5),
  value = rnorm(15)
)
measure_ndim(m2d)  # 2
#> [1] 2
