LandscapePlot: A function to visualize the Functional Landscape of measured...

In multiDimBio: Multivariate Analysis and Visualization for Biological Data

Description

This function plots a three-dimensional landscape of measured traits. The peak heights are relative with respect to the input data. The width of each peak is controlled by the argument sigma and has only an aesthetic purpose. The 3D image is generated using the drawScene and surfaceTriangles .

Usage

LandscapePlot(Data, Groups=NULL, PDF=FALSE,LocPlot=FALSE,control=c(75,1,30))

Arguments

Data	A (non-empty) numeric matrix with trait values
Groups	A (non-empty)factor vector indicating the group membership of each row in Data. If there is only a single group present in Data then Groups=NULL (default).
PDF	Logical controlling whether to output the results as a .pdf or a .jpeg. The default (PDF=FALSE) will produce a .jpeg. The file size for .pdf output can be large.
LocPlot	Logical controlling whether to output a .pdf naming the peaks according to the columns they represent. The defaul is FALSE.
control	An optional numeric vector setting the control parameters for persp. control[1] = theta, control[2] = r, control[3] = phi

Value

a list of plots stored as grid plots (or.pdf if PDF=TRUE) file for each column in data.

Examples

data(Nuclei) 
data(Groups)
 
#plotting the first six columns
#not run
#LandscapePlot(Nuclei[,1:6], Groups=Groups)
