plot.mixedMemModel: Plot a Mixed Membership Model
In mixedMem: Tools for Discrete Multivariate Mixed Membership Models

Generic S3 function to produce visual representation of a mixedMemModel object. This function calls either the vizTheta or the vizMem function.

## S3 method for class 'mixedMemModel'
plot(x, type = "theta", compare = NULL,
  main = NULL, varNames = NULL, groupNames = NULL, nrow = NULL,
  ncol = NULL, indices = NULL, fitNames = NULL, ...)

`x`	the `mixedMemModel` object to be plotted.
`type`	a string which indicates which estimated parameters to plot; valid options are "theta" or "membership". `vizTheta` is called when the type is "theta" and `vizMem` is called when the type is "membership".
`compare`	an array or matrix for comparison. When type = "theta", `compare` should be an array the same size as x$theta. When type = "membership", `compare` should be a matrix the same size as x$phi.
`main`	the main figure title.
`varNames`	a vector of strings corresponding to names for each variable if plot type is theta.
`groupNames`	a vector of strings corresponding to labels for each sub-population.
`nrow`	the number of rows for the grid of plots.
`ncol`	the number of columns for the grid of plots. If plot type is "theta", this must be K, if plot type is "membership", this must be a positive integer.
`indices`	a vector of integers. If the plot type is "membership", this indicates which individuals to plot. When plot type is "theta", this indicates which variables to plot.
`fitNames`	a vector of strings corresponding to labels for each fit.
`...`	additional parameters to be passed.
