plot.relationshipMatrix: Heatmap for relationship Matrix

Description

Visualization for objects of class relationshipMatrix using a heatmap of pairwise relatedness coefficients.

Usage

## S3 method for class 'relationshipMatrix':
plot(x, levelbreaks=NULL, \ldots)

Arguments

x

Object of class relationshipMatrix

levelbreaks

Defined breaks in the color scheme of the levelplot. If you make to many breaks, the color scheme repeats!

...

further graphical arguments passed to function levelplot in package lattice. To create equal colorkeys for two heatmaps, use at=seq(from,to,length=9).

Examples

# small pedigree
ped <- simul.pedigree(gener=4,7)
gp <- create.gpData(pedigree=ped)
A <- kin(gp,ret="add")
plot(A)

# big pedigree
library(synbreedData)
data(maize)
K <- kin(maize,ret="kin")
U <- kin(codeGeno(maize),ret="realized")/2
# equal colorkeys
plot(K,levelbreaks=seq(0,2,length=9))
plot(U,levelbreaks=seq(0,2,length=9))
