[R] good boosting tutorial and package in R?

[Michael]

Hi all,

Could you please give me some pointers about what's the best boosting
package in R currently?

in terms of classification accuracy?

And any pointers about tutorials and study-materials to curb the
learning curve will be greatly appreciated!

Thank you!

p.s. Does anybody happen to know Boosting implemented in other
language such as Matlab?

Are they good in terms of accuracy?

What are the other competing tools for classification?

Any literature paper/tutorial on comparisons?

Thank you!
