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)

...e[-zbior.uczacy,],"class") #data frames with my result from klasyfikatorKNN df=data.frame(glucose=c(klasyfikatorKNN$learn$X[,1]),insulin=klasyfikatorKNN$learn$X[,2],diabetes=c(klasyfikatorKNN$learn$y)) #And picture drawparti(as.factor(df$diabetes), df$glucose, df$insulin, method = "sknn", prec = 100, xlab = NULL, ylab = NULL) ########################## My question is: How or where may I find correct or wrong values which were drawn (found,classification) in this picture? It means I'm looking for x, y values. -- View this message in context: http://www.nabble.com/%...

Hi! I got the following runtime error when I tried to use svm method with stepclass. Error in "colnames<-"(`*tmp*`, value = c("0", "1")) : attempt to set colnames on object with less than two dimensions I repeated the same sequence of statements but this time I used the classification function used in the example, i.e., "lda" and it worked fine
