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.Length + Sepal.Width + Petal.Length + Petal.Width, data = iris) LD1<-predict(iris.lda)$x[,1] LD2<-predict(iris.lda)$x[,2] ggplot(iris, aes(x=LD1, y=LD2, col=iris$Species) ) + geom_point( size = 4, aes(color = iris$Species))+theme_bw()
Could someone please help me. Thank you very much. -- View this message in context: http://r.789695.n4.nabble.com/LDA-and-confidence-ellipse-tp4671308.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
