(math/R-classInt) Updated 0.4.10 to 0.4.11, make test passed

## Version 0.4-11

- #49 explicitly forbid use of `"quantile"` style `probs=` argument;
   should really use `n=`, as `probs` is set internally to `seq(0, 1,
   1/n)`. Similarly, forbid `centers=` argument in `"kmeans"` and
   `"bclust"` styles as it is set internally to `n`.
