[R] Evaluating statistical models and describing coefficients for non-parametric models

Hi All,

I'm using number of models such as lm(), tree, randomForest, svm, and nnet for predicting the delays in projects. Also, I computed the sum of  squared error for all these models for comparison purposes. However, I want to use other related evaluation criteria such as root mean sum of square error (RMSE) and R Squared for evaluation of these models.

My question is that is it possible to compute these criteria (RMSE or R2) for all above-mentioned statistical models.

Second, for the lm() we can see the co-efficient values by checking model summary. Is it possible to see the co-efficient for other models such as SVM and neural network?

Thanks in advance for the help and support.

Many Thanks and

Kind Regards
