show_digit

Plots an image of a grayscale grid representation of a digit.

plotting

Provides flexible Bayesian estimation of Infinite Mixtures of Infinite Factor Analysers and related models, for nonparametrically clustering high-dimensional data, introduced by Murphy et al. (2020) <doi:10.1214/19-BA1179>. The IMIFA model conducts Bayesian nonparametric model-based clustering with factor analytic covariance structures without recourse to model selection criteria to choose the number of clusters or cluster-specific latent factors, mostly via efficient Gibbs updates. Model-specific diagnostic tools are also provided, as well as many options for plotting results, conducting posterior inference on parameters of interest, posterior predictive checking, and quantifying uncertainty.

<dl><dt>dat</dt>
<dd>A <code>matrix</code> or <code>data.frame</code> with the same number of rows and columns (or a vector which can be coerced to such a format), representing a grayscale map of a single digit.</dd>
<dt>col</dt>
<dd>The colour scale to be used. Defaults to <code>grey(seq(1, 0, length = ncol(dat)))</code>.</dd>
