Re: [R] LDA and confidence ellipse

Hi, May be this helps: require(MASS) require(ggplot2) iris.lda<-lda(Species ~ Sepal.Length + Sepal.Width + Petal.Length + Petal.Width,  data = iris) datPred<-data.frame(Species=predict(iris.lda)$class,predict(iris.lda)$x) library(ellipse) dat_ell <- data.frame() for(g in levels(datPred$Species))

[R] LDA and confidence ellipse

Hi, I wish to add confidence ellipse on my LDA result of the iris data set. Therefore: Is there statistical logic to do that as I only wish it to make the species separation more visable? How can I add it to the script below (ggplot): require(MASS) require(ggplot2) iris.lda<-lda(Species ~ Sepal.
