In rminer: Data Mining Classification and Regression Methods

VEC plot function (to use in conjunction with Importance function).

Description

VEC plot function (to use in conjunction with Importance function).

Usage

vecplot(I, graph = "VEC", leg = NULL, xval = 1, sort = FALSE, data = NULL, 
digits = c(1, 1), TC = 1, intbar = NULL, lty = 1, pch = 19, col = NULL, 
datacol = NULL, main = "", main2 = "", Grid = 0, 
xlab = "", ylab = "", zlab = "", 
levels = NULL, levels2 = NULL, showlevels = FALSE, 
screen = list(z = 40, x = -60), zoom = 1, cex = 1)

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
