Learn Support Vector Machine (SVM) from Scratch in R

Imagine a case - if there is no straight line (or hyperplane) which can separate two classes? In the image shown below, there is a circle in 2D with red and blue data points all over it such that adjacent data points are of different colors. SVM handles the above case by using a kernel function to handle non-linear separable data. It is explained in the next section. In simple words, it is a method to make SVM run in case of non-linear separable data points.
