Hi, As a number of people suggested, I downloaded the "e071" package and am using the function "svm" for my classification problem. I now want to take the classifier outside the R environment, for example to a C program, and use it. I know that the classifer is of the form WTX+b where W is defined by the support vectors. I did not see that W vector is output from svm. If am I right how should I compute it? Is b output? Thanks Meir ******************************************** Meir Preiszler - Research Engineer I t a m a r M e d i c a l Ltd.
