Hello, if I try to tune my svm with the code: Tune <- tune.svm(Data.Train, Class.Train, type="C-classification", kernel="radial", gamma = 2^(-1:1), cost = 2^(2:4)) i get a windows Messagebox with a error in the application "Rgui.exe" and the message: "Die Anweisung in 0x6c48174d verweist auf Speicher 0x00000000. Der Vorgang "read" konnte nicht auf dem Speicher ausgef??hrt werden. ....." is this a known error, or is there any mistake in my code? regards Andreas

That looks like dereferencing a null pointer. It's likely in the e1071 code, not actually in Rgui. Duncan Murdoch
