O.k. - sorry for my sparse information. I just made an update to R-2.10.1 and e1071 version 1.5-22 on WinXP. I can reproduce the example with the iris dataset. However R crashes when I call svm() with my dataset model <- svm(soil_unit ~ ., data = traindat, type="nu-classification") My dataset consists of 9259 obs. of 14 variables. My target variable is a factor variable with 22 levels (multi-class classification). Predictors are 12 numeric and 1 factor variables. Hoping this information is enough.
