Validate a mass properties table

validate_mass_props_table() checks that the names of vertices in a tree and the id values of a data frame are identical. It further applies the checks of validate_mass_props() to every row of the data frame corresponding to a leaf vertex of the tree.

validate_mass_props_table() ensures that the id column of the table and the vertices of the tree contain the same identifiers, and that the mass properties of every leaf element of the table are valid.

Usage

validate_mass_props_table(tree, df)

Arguments

tree

An 'igraph' tree whose vertices are named as the values of the id column of df and whose directed edges point from child id to parent id.

df

A data frame with (at least) these columns: id, mass, Cx, Cy, Cz, Ixx, Iyy, Izz, Ixy, Ixz, Iyz, POIconv, Ipoint.

Value

TRUE if valid, stops with an error otherwise

Examples

validate_mass_props_table(mp_tree, mp_table)
#> [1] TRUE
