Get grid information for an n-dimensional measurement

Returns detailed information about the coordinate grid, including unique values per dimension, grid shape, and regularity status.

Usage

measure_grid_info(x)

Arguments

x

A measure_nd_tbl object.

Value

A list with components:

• ndim: Number of dimensions

• dim_names: Semantic dimension names (if set)

• dim_units: Dimension units (if set)

• unique_values: List of unique coordinate values per dimension

• shape: Integer vector of unique value counts per dimension

• n_points: Total number of data points

• is_regular: Whether the grid is regular

• has_na: Whether any values are NA

Examples

m2d <- new_measure_nd_tbl(
  location_1 = rep(seq(0, 10, by = 2), each = 4),
  location_2 = rep(c(254, 280, 320, 350), times = 6),
  value = rnorm(24),
  dim_names = c("time", "wavelength"),
  dim_units = c("min", "nm")
)
