Joao: The reported error message is not from e1071. How *exactly* did you call svm()?
As to the documentation of the nu parameter: yes, this is an omission, of course, nu is used in nu-regression as well; thanks for pointing this out. best, David --------- Hello, I am using SVM under e1071 package for nu-regression with 18 parameters. The variables are ordered factors, factors, date or numeric datatypes. I use the linear kernel. It gives the following error that I cannot solve. I tryed debug, browser and all that stuff, but no way. The error is: Error in get(ctr, mode = "function", envir = parent.frame())(levels(x), : Orthogonal polynomials cannot be represented accurately enough for 236 degrees of freedom I use the nu parameter. However, reading ?svm help it says "parameter needed for 'nu-classification' and 'one-classification'". Does not say anything about nu-regression. It is an omission in the ?svm help page? Or am I notundestanding something? I believe it has something to do with the calculus of the eigenvalues. Anyway how can I overpass this problem? Increasing the training data (is around 900 records)?
