Defunct Functions in Package prefmod

Description

A list of functions that are no longer part of prefmod.

Usage

plotworth(worthmat, main = "Preferences", ylab = "Estimate", psymb = NULL,
        pcol = NULL, ylim = range(worthmat), ...)

Arguments

worthmat

parameter matrix as generated from llbt.worth or patt.worth.

main

main title of the plot.

ylab

y-axis label

psymb

plotsymbols for objects, see Details below

pcol

colours for objects, see Details below

ylim

limits for y-axis

...

further graphical parameters, use e.g. log = "y" to obtain a logarithmic plot

Details

plotworth() was initially used to plot worth or model parameters from LLBT or pattern models (in a matrix created by llbt.worth() or patt.worth()). Now, the generic plot (i.e., plot.wmat()) has to be used.
