Plot the Entry Order in an fwdmv Object

Description

Produces an entry order plot of an fwdmv object.

Usage

fwdmvEntryPlot(x, entry.order = "first", subset.size = -1, psfrag.labels = FALSE)

Arguments

x an fwdmv object.
entry.order a character vector of length 1 specifying how the rows should be ordered. The possibilities are "first", "final", "natural" and "integer". If entry.order == "integer" then entry.order.n must be supplied as well.
subset.size an integer value giving the subset size to be used when entry.order == "integer".
psfrag.labels a logical value. If TRUE then the x, y, and main labels are set to "xlab", "ylab", and "main" for replacement via the psfrag utility.

Details

An entry oder plot is a matrix where the (i,j) cell is black if the unit represented by row i is in the subset during step j and white otherwise. The rows can be ordered in four ways: (1) First entry order: the rows are ordered (from bottom to top) by the first time the unit enters the subset; (2) Final entry order: the row are ordered (from bottom to top) by the last time the unit enters the subset; (3) Natural entry order: the rows appear (from bottom to top) in the same order as in the data; and (4) Integer entry order: the rows are ordered (from bottom to top) in the same order as the distances in the subset of subset.size units.

Value

an empty list is returned invisibly.
