Construct a Minimum Viable Data Frame object

mvdf_obj(
  data = NULL,
  x = "x",
  y = "y",
  z = "z",
  idx = "idx",
  metadata = NULL,
  appendix = NULL
)

Arguments

data	Optionally, a data frame containing all the data necessary to create a `mvdf_obj`. If left `NULL`, then `x`, `y`, `z`, and `idx` are interpreted as the values to use for each slot; if not `NULL`, `x`, `y`, `z`, and `idx` are interpreted as the names of columns in `data` containing the values for each slot.
x, y, z	Numeric: distance of the origin of the object from the origin of the grid system (the central point at 0, 0, 0) in meters in the given direction. Must have no `NA`, `NULL`, `NaN`, `Inf`, or `-Inf` values. If `data` is not `NULL`, the names of columns in `data` with values for the respective slot. Coordinates are assumed to be on a right-handed coordinate system with Z oriented as the natural "vertical" direction.
idx	Character: a unique identifier (or "index") for each object to be modeled. Must be unique with no `NA` or `NULL` values, but otherwise is not validated. If `data` is not `NULL`, the names of columns in `data` with values for the slot. If left `NULL`, a sequential index is generated.
metadata	Data frame: a table containing additional information on the objects to be modeled. Optional, but if this slot is used then the data frame must contain a column named `idx` which should correspond to the `idx` slot. Only the existence of this column is validated.
appendix	List: additional data produced in the generation of the object. Not validated; any additional outputs that don't map to modeled objects may be inserted here.
