x_constraint: Fixes particles to a horizontal position

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

Fixes particles to a horizontal position

Description

This constraint simply prevents particles from moving in the x direction. For particles where the constraint evaluates to NA this constraint is ignored. If the constraint is enforced the velocity in the x 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()

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

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

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