torusAxis

Wrapper for drawing pretty axis labels for circular variables.
To be invoked after <code>plot</code> with <code>axes = FALSE</code> has been called.

Implementation of statistical methods for the estimation of
toroidal diffusions. Several diffusive models are provided, most of them
belonging to the Langevin family of diffusions on the torus. Specifically,
the wrapped normal and von Mises processes are included, which can be seen
as toroidal analogues of the Ornstein-Uhlenbeck diffusion. A collection of
methods for approximate maximum likelihood estimation, organized in four
blocks, is given: (i) based on the exact transition probability density,
obtained as the numerical solution to the Fokker-Plank equation; (ii) based
on wrapped pseudo-likelihoods; (iii) based on specific analytic
approximations by wrapped processes; (iv) based on maximum likelihood of
the stationary densities. The package allows the replicability of the
results in García-Portugués et al. (2019) <doi:10.1007/s11222-017-9790-2>.

<dd>an integer vector specifying which side of the plot the axes are
to be drawn on. The axes are placed as follows: <code>1</code> = below,
<code>2</code> = left, <code>3</code> = above, and <code>4</code> = right.</dd>
