y_constraint: Fixes particles to a vertical position

In thomasp85/particles: A Graph Based Particle Simulator Based on D3-Force

Fixes particles to a vertical position

Description

This constraint simply prevents particles from moving in the y direction. For particles where the constraint evaluates to NA this constraint is ignored. If the constraint is enforced the velocity in the y direction will be set to 0.

Training parameters

The following parameters defines the training of the constraint and can be passed along a call to impose()

• y : The position on the y-axis to fix to. (tidy eval)

• ymin : The lowest permissible y-value. If NULL then y will be used. (tidy eval)

• ymax : The highest permissible y-value. If NULL then y will be used. (tidy eval)
