R: Plot the output of 'VariationalBayes'

plot.vb {LaplacesDemon} | R Documentation

## Plot the output of `VariationalBayes`

### Description

This may be used to plot, or save plots of, the iterated history of the parameters and variances, and if posterior samples were taken, density plots of parameters and monitors in an object of class `vb`.

### Usage

    ## S3 method for class 'vb'
    plot(x, Data, PDF=FALSE, Parms, ...)

### Arguments

`x` | This required argument is an object of class `vb`.
`Data` | This required argument must receive the list of data that was supplied to `VariationalBayes` to create the object of class `vb`.
`PDF` | This logical argument indicates whether or not the user wants Laplace's Demon to save the plots as a .pdf file.
`Parms` | This argument accepts a vector of quoted strings to be matched for selecting parameters for plotting. This argument defaults to `NULL` and selects every parameter for plotting. Each quoted string is matched to one or more parameter names with the `grep` function. For example, if the user specifies `Parms=c("eta", "tau")`, and if the parameter names are beta[1], beta[2], eta[1], eta[2], and tau, then all parameters will be selected, because the string `eta` is within `beta`. Since `grep` is used, string matching uses regular expressions, so beware of meta-characters, though these are acceptable: ".", "[", and "]".
`...` | Additional arguments are unused.

### Details

The plots are arranged in a 3 x 3 matrix. The purpose of the iterated history plots is to show how the value of each parameter, variance, and the deviance changed by iteration as the `VariationalBayes` attempted to maximize the logarithm of the unnormalized joint posterior density. If the algorithm converged, and if `sir=TRUE` in `VariationalBayes`, then plots are produced of selected parameters and all monitored variables.
