I implemented a LS-SVM model development using e1071 package in R platform. The dataset was only 20 (X and Y). I obtained a good fit using tune function. I used RBF kernel.

Now, i would like to have the non-linear functional relationship  between independent variable (X) and dependent variable (Y), which can facilitate to apply the model even in spreadsheet calculation purpose.

Is there any way to write the non-linear model equation/functional relationship between dependent and independent variables for a LS-SVM example. Thanks in advance.
