Check that a structure is internally consistent

Checks the rules a structure has to satisfy:

• points are unique and not NA;

• every segment joins two known, different points, and any expected length is positive;

• every joint pairs two different, defined segments, about an axis that is "x", "y", "z" or a segment name;

• a joint's min is not above its max, and its rest lies between them;

• root is one of the points, or NA.

anistructure() and set_structure() call it, so a structure built there is already valid; call it yourself after editing a structure's parts by hand.

Usage

validate_anistructure(x)

Arguments

x

An anistructure.

Value

x, invisibly; errors naming the first problem otherwise.

Examples

validate_anistructure(example_structure())
