Arguments

I

the output list of the Importance function.

graph

type of VEC graph:

  • VEC – 1-D VEC curve;

  • VECB – 1-D VEC curve with box plots (only valid for SA methods: "DSA", "MSA");

  • VEC3 – 2-D VEC surface;

  • VECC – 2-D VEC contour;

leg

see mgraph

xval

the attribute input index (e.g. 1), only used if graph="VEC" or (graph="VEC3" or "VECC" and length(interactions)=1, see Importance). if a vector, then several VEC curves are plotted (in this case, x-axis is scaled).

sort

if factor inputs are sorted:

  • increasing – sorts the first attribute (if factor) according to the response values, increasing order;

  • decreasing – similar to increasing but uses reverse order;

  • TRUE – similar to increasing;

  • increasing2 – sorts the second attribute (for graph="VEC3" or "VECC", if factor, according to the response values), increasing order;

  • decreasing2 – similar to increasing2 but uses reverse order;

  • FALSE – no sort is used;

data

see mgraph

digits

see mgraph

TC

see mgraph

intbar

see mgraph

lty

see mgraph

pch

point type for the graph="VEC" curve, can be a vector if there are several VEC curve plots

col

color (e.g. "black", "grayrange", "white")

datacol

color of the data histogram for graph="VEC"

main

see mgraph

main2

key title for graph="VECC"

Grid

see mgraph

xlab

x-axis label

ylab

y-axis label

zlab

z-axis label

levels

if x1 is factor you can choose the order of the levels to this argument

levels2

if x2 is factor you can choose the order of the levels to this argument

showlevels

if you want to show the factor levels in x1 or x2 axis in graph="VEC3":

  • FALSE or TRUE – do not (do) show the levels in x1, x2 and z axis for factor variables;

  • vector with 3 logical values – if you want to show the levels in each of the x1, x2 or z axis for factor variables (e.g. c(FALSE,FALSE,TRUE) only shows for z-axis).

screen

select the perspective angle of the VEC3 graph:

  • x – assumes list(z=0,x=-90,y=0);

  • X – assumes list(x=-75);

  • y – assumes list(z=0,x=-90,y=-90);

  • Y – assumes list(z=10,x=-90,y=-90);

  • z – assumes list(z=0,x=0,y=0);

  • xy – assumes list(z=10,x=-90,y=-45);

  • else you need to specify a list with z, x an y angles, see wireframe

zoom

zoom of the wireframe (graph="VEC3")

cex

label font size
