dOFV.vs.id: Change in Objective function value vs. removal of individuals.

Description

A plot showing the most and least influential individuals in determinning a drop in OFV between two models.

Usage

dOFV.vs.id(xpdb1,
             xpdb2,
             sig.drop=-3.84,
             decrease.label.number=3,
             increase.label.number=3,
             id.lab.cex=0.6,

             type="o",
             xlb="Number of subjects removed",
             ylb=expression(paste(Delta,"OFV")),

                    expression(paste("Significant  ",Delta, OFV)),
                    expression(paste("Total  ",Delta, OFV))

ylb

Y-axis label.

main

Title of plot.

sig.line.col

Significant OFV drop line color.

Examples

library(xpose4)

## first make sure that the iofv values are read into xpose
cur.dir <- getwd()
setwd(paste(cur.dir,"/LAG_TIME",sep=""))
xpdb1 <- xpose.data(1)
setwd(paste(cur.dir,"/TRANSIT_MODEL",sep=""))
xpdb2 <- xpose.data(1)
setwd(cur.dir)

## then make the plot
dOFV.vs.id(xpdb1,xpdb2)
