...hat's posiible for me make any calculaton's with variables in the 64 subset's. Example: I want calculate difference of two variables inside every of the 64 subset data.frames and getting this value in tList!

hello, i am so glad to write you. i am dealing now with writing my M.Sc in Applied Statistics thesis, titled " Data Mining Classifiers and Predictive Models Validation and Evaluation". I am planning to compare several DM classifiers like "NN, kNN, SVM, Dtree, and Naïve Bayes" according to their Predicting accuracy, interpretability, scalability, and time consuming etc. I have faced a problem when I am writing the classification table using R The problem is facing me at the last command. The error is : " tab <- table(pred = prediction, true...

Hi everyone, Could somebody explain to me what is the package/function for classification analysis. I am performing analysis of music files in the form of MIDI files. I end up with about 750 dependent variables from the analysis, I also have a number of independent/grouping variables that I set manually. What I would like is to be able to predict which group a particular MIDI files belongs to
