Arguments

x	a data frame created by impute.yai, or an object created by yai.
vars	a list of variable names you want to include, if NULL all available Y-variables are included.
pointColor	a color vector for the xy plots (continuous variables).

data(iris)

# form some test data
refs=sample(rownames(iris),50)
x <- iris[,1:3]      # Sepal.Length Sepal.Width Petal.Length
y <- iris[refs,4:5]  # Petal.Width Species

mal <- yai(x=x,y=y,method="mahalanobis")
malImp=impute(mal,newdata=iris)
plot(malImp)
