Description Usage Arguments Examples
model from RSSL package
Implementation of the Linear Support Vector Classifier. Can be solved in the Dual formulation, which is equivalent to SVM
or the Primal formulation.

C |
Cost variable |
Cstar |
numeric; Cost parameter of the unlabeled objects |

logical; Should the features be centered? |
scale |
Whether a z-transform should be applied (default: TRUE) |
eps |
Small value to ensure positive definiteness of the matrix in QP formulation |
