Hi there, I classified an image and checked out it on the field. Now I have a table with three fields like: Field_ID Field_Class Image_Class 1 1 1 2 3 5 3 4 1 4 1 1 5 2 1 ... And now I need gerating a confusion matrix to compute Kappa statistic. First of all, how can I generate the confusion matrix from my input table? What package is good for compute Kappa statistics? Regards, Miltinho Brazil
