How it works...
The e1071 package provides miscellaneous functions to build and assess models; therefore, you do not need to reinvent the wheel to evaluate a fitted model. In this recipe, we use the tune.svm function to tune the svm model with the given formula, dataset, gamma, cost, and control functions. Within the tune.control options, we configure the option as cross=10, which performs a 10-fold cross validation during the tuning process. The tuning process will eventually return the minimum estimation error, performance detail, and the best model during the tuning process. Therefore, we can obtain the performance measures of the tuning and further use the optimum model to generate a classification table.
