Arguments

x	An object expected to be of class "sl_stand".

Details

The following validations are performed:

• The object inherits from class "sl_stand".

• The top-level components trees, sensors, cells, core_polygon, transform, geometry and inventory are present.

• The trees data.frame passes check_inventory.

• The sensors data.frame passes check_sensors.

• The cells data.frame contains columns x_center, y_center, z_center, and id_cell.

• The geometry list contains cell_size, n_cells_x, n_cells_y, slope, aspect, and north2x.

• All trees and sensors lie within the bounds of the rectangular stand.
