[R] Manually calculate SVM

I'm learning more about SVMs and kernels in general. I've gotten used
to using the svm function in the e1071 package. It works great.
Now, I want to do/learn some more interesting stuff. (Perhaps my own
kernel and/or scoring system). So I want to better understand
1) how calculation of the kernel happens.
2) how to calculate the predicted value (y_hat) given a list of support
vectors and coefficients.
I've seen all the formulas and many of the books. I get most of it
conceptually. Where I'm having trouble is making the leap from concept
to actual use. Ideally, I'd love to code some of the basic stuff in R
or Perl in scratch. It won't be efficient, but will better help me
understand just how actual values are manipulated.
I know this isn't the function of the list, but was hoping that someone
could point me toward some good resources or offer some suggestion.
