Hi I want to create a nice picture about my result of k -the nearest neighbours algorithm. Here is my easy code: ################################# library(klaR) library(ipred) library(mlbench)
data(PimaIndiansDiabetes2) dane=na.omit(PimaIndiansDiabetes2)[,c(2,5,9)] dane[,2]=log(dane[,2]) dane[,1:2]=scale(dane[,1:2]) zbior.uczacy=sample(1:nrow(dane),nrow(dane)/2,F) KNN=ipredknn(diabetes~glucose+insulin,data=dane,subset=zbior.uczacy,k=3) KNN=ipredknn(diabetes~glucose+insulin,data=dane,subset=zbior.uczacy,k=3) b= ifelse((a==1),'red','blue' ) a=as.numeric(KNN$learn$y) plot(KNN$learn$X[,1], KNN$learn$X[,2],pch=a,col = ifelse((a==1),'red','blue' )) ################################# and my problem is (it's difficult for me to explain it in english): What I should do if I want to get in my picture area (in different colors) which will be show my "clasters". Like in picture (dark blue and bright blue). http://n4.nabble.com/file/n1585911/dec.jpg -- View this message in context: http://n4.nabble.com/create-picture-k-the-nearest-neighbours-tp1585911p1585911.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.
