covplot: scree-ploting cov(X, Y)

Description

Returns a scree-plot of the eigenvalues of cov(first.set, second.set) to select its first d largest eigenvectors.

Usage

covplot(X, Y, mind=NULL)

Arguments

X

numeric matrix (n * p), X

Y

numeric matrix (n * r), Y

mind

numeric, the number of the eigenvalues to show their cumulative percentages. The default is NULL, and then it is equal to min(p,r)

Value

eigenvalues

the ordiered eigenvalues of cov(X,Y)

cum.percent

the cumulative percentages of the eigenvalues

num.evecs

a vector of the numbers of the eigenvectors which forces the cumulative percentages bigger than 0.6, 0.7, 0.8, 0.9

Examples

# NOT RUN {
data(cookie)
myseq<-seq(141,651,by=2)
X<-as.matrix(cookie[-c(23,61),myseq])
Y<-as.matrix(cookie[-c(23,61),701:704])
covplot(X, Y)
covplot(X, Y, mind=4)
# }
