blur_point

Animation of observed trajectories using spline-based interpolation (see for example, Buderman, F. E., Hooten, M. B., Ivan, J. S. and Shenk, T. M. (2016), <doi:10.1111/2041-210X.12465> "A functional model for characterizing long-distance movement behaviour". Methods Ecol Evol). Intended to be used exploratory data analysis, and perhaps for preparation of presentations.

blur_point function

<dl><dt>x</dt>
<dd>An object. In the default method the parameter x should be a correlation between -1 and 1 or a square positive definite matrix at least 2x2 in size. It will be treated as the correlation or covariance of a multivariate normal distribution.</dd>
<dt>levels</dt>
<dd>contour levels</dd>
<dt>alpha_mult</dt>
<dd>multiplier on transparency level</dd>
<dt>col</dt>
<dd>default is black</dd>
<dt>center</dt>
<dd>two-vector giving center of ellipse</dd></dl>
