Using R Caret model with different tunning parameters

I trained a NNET Caret Model with three sizes in tuning function.The final Model was fitted with one size. It was choosed by the smallest RMSE, automatically.

    Neural Network 9700 samples  23 predictorPre-processing: centered, scaled Resampling: Cross-Validated (8 fold, repeated 8 times) Summary of sample sizes: 8488, 8488, 8487, 8485, 8488, 8488, ... Resampling results across tuning parameters:  size  RMSE    Rsquared  RMSE SD   Rsquared SD  12    0.0328  0.951     0.002033  0.006127     24    0.0221  0.978     0.001358  0.002764     72    0.0134  0.992     0.000647  0.000815   Tuning parameter 'decay' was held constant at a value of 5e-04RMSE was used to select the optimal model using  the smallest value.The final values used for the model were size = 72 and decay = 5e-04. 

But I want to explore the models trained with the others sizes too.Can I use the the predict function with others tunning parameters of the model?
