[R] Model after random forest

Hi there, I´m using random Forest package to create a random Forest: model<-randomForest(A~.,data=mydata) , and I use the varImpPlot(model) to see which are the most important variables, so I obtain that C, D and F are the most important ones, but... How can I see the model, in which levels I

Re: [R] For logical i and length(i) > length(x), x[i] <- value makes length(x) == length(i)

Thank you for looking. If the last element of i is TRUE, the largest value of which(i) is length(i). So, even if x[i] <- value were translated to x[which(i)] <- value, the result would have length(x) == length(i). Difference between x[i] <- value and x[which(i)] <- value in R would occur when

Re: [R] Please read **Urgent** Need help with R

Hi Mehmet, Did you send this in HTML? That's what it looks like. It is currently almost unreadable. You need to reformat it and send it as plain text. You need to reduce the code to the key parts if possible. It looks like most of the code is unneeded for the problem and is just a distraction.

Re: [R] For logical i and length(i) > length(x), x[i] <- value makes length(x) == length(i)

>>From it, I infer that, if i is logical and length(i) >= length(x), x[i] <- >>value has >the same effect to x[which(i)] <- value, where which(i) takes >>indices where i is >T. The return value of which(i) gives only the indices of the TRUE values in i. It does not return the length of i.

Re: [R] a question about data manipulation in R

You are in the right place but the question in not very clear. Have a look at the links below for some suggestions on how to ask a question on R-help. I think we need the data in dput() format. See ?dput or the discussion of dput() in the links.

Re: [R] kendall tau distance

The function takes a two way table. Assuming your example involves two ordinal vectors c(1,2,3,4,5) and c(3,4,1,2,5), you need: > xy <- table(c(1,2,3,4,5),c(3,4,1,2,5)) > xy 1 2 3 4 5 1 0 0 1 0 0 2 0 0 0 1 0 3 1 0 0 0 0 4 0 1 0 0 0 5 0 0 0 0 1 > cd <- ConDisPairs(xy) > cd $pi.c
