%description
Kernel functions for diverse types of data (including, but not restricted
to: nonnegative and real vectors, real matrices, categorical and ordinal
variables, sets, strings), plus other utilities like kernel similarity,
kernel Principal Components Analysis (PCA) and features' importance for
Support Vector Machines (SVMs), which expand other 'R' packages like
'kernlab'.
