plot.plfm: plot parameters in plfm object

Description

Plot method to visualize the parameters of probabilistic feature models.

Usage

# S3 method for plfm
plot(x,feature=1,element="object",cexsymb=1,cexlabel=1,...)

Arguments

x

Probabilistic feature model object returned by plfm.

feature

Latent feature for which parameters are visualized.

element

Object parameters are plotted if element="object" and attribute parameters are plotted if element="attribute".

cexsymb

Size of symbol used for plotting points.

cexlabel

Size of object- or attribute labels in plot.

...

Further arguments are ignored.
