Hi Sacha, On second thought, perhaps this is more the direction that you want ... X2 = cbind(X_train,y_train) colnames(X2)[3] = "y" regr2<-randomForest(y~x1+x2, data=X2,maxnodes=10, ntree=10) regr regr2 #Make prediction predictions= predict(regr, X_test) predictions2= predict(regr2, X_test) HTH, Eric On Tue, May 9, 2023 at 6:40?AM Eric Berger <ericjberger at gmail.com>

Greetings, I have been exploring the use of the caret package to conduct some plsda modeling. Previously, I have come across methods that result in a R2 and Q2 for the model. Using the 'iris' data set, I wanted to see if I could accomplish this with the caret package. I use the following code: library(caret) data(iris) #needed to convert to numeric in order to do regression #I

Dear R-experts, Here below a toy example with some error messages, especially at the end of the code (Tuning the parameters). Your help to correct my R code would be highly appreciated. ####################################### #libraries library(lattice) library(ggplot2) library(caret) library(randomForest) ?? #Data

I have never been able to get class probabilities to work and I am relatively new to using these tools, and I am looking for some insight as to what may be wrong. I am using caret with kernlab/ksvm. I will simplify my problem to a basic data set which produces the same problem. I have read the caret vignettes as well as documentation for ?train. I appreciate any direction you can give. I

I am using the denoiser and AGC, but the problem persists if I turn them off (stop calling speex_preprocess() altogether). Also, I have reproduced it on both a noisy system and a quiet system that hardly needs the denoiser. I know what you mean though, I have heard similar sounds when pushing the denoiser too hard. For example, doing 100x AGC, or trying to use an extension cord with my microphone...

I'm using caret to assess classifier performance (and it's great!). However, I've found that my results differ between R2.* and R3.* - reported accuracies are reduced dramatically. I suspect that a code change to kernlab ksvm may be responsible (see version 5.16-24 here: http://cran.r-project.org/web/packages/caret/news.html). I get very different results between caret_5.15-61 +

Hi, I need to install windows services remotely from linux. Given that the windows server is running with minimum credentials. On reading hte previous mails, I found that it is possible using jarapac, midlc, jcifs etc. So I started with jcifs. I am able to transfer a file(service) from linux to windows using jcifs API. Now I want to start that service. First I tried with installing midlc

I have a grown list of IPs that I am "deny ip from ###.### to any". Infected machines, hackers, etc.. Is there a way to have this list outside of rc.firewall and just read it in?
