var.complr

Variance of compositions presented in a <code>complr</code> object.

Implement Bayesian multilevel modelling for compositional data.
Compute multilevel compositional data and
perform log-ratio transforms at between and within-person levels,
fit Bayesian multilevel models for compositional predictors and outcomes,
and run post-hoc analyses such as isotemporal substitution models.

var.complr function

<dl><dt>x</dt>
<dd>An object of class <code>complr</code>.</dd>
<dt>weight</dt>
<dd>A character value specifying the weight to use in calculation of the reference composition.
If <code>"equal"</code>, give equal weight to units (e.g., individuals).
If <code>"proportional"</code>, weights in proportion to the frequencies of units being averaged
(e.g., observations across individuals)
Default is <code>equal</code>.</dd>
<dt>parts</dt>
<dd>A optional character string specifying names of compositional parts that should be considered
in the substitution analysis. This should correspond to a single set of names of compositional parts specified
in the <code>complr</code> object. Default to the first composition in the <code>complr</code> object.</dd>
<dt>...</dt>
<dd>generic argument, not in use.</dd></dl>
