[R] imbalanced data set

[Weiwei Shi]

Hi, 
I have a question of classification on imbalanced dataset. I am
wondering if there is a package which can solve this problem via
sampling approach, like one-sided selection.

A follow-up question is, how to select those 'representative' samples
and remove noise/borderlines and redundancy in order to increase
classification accuracy. Is there any work which has been implemented
in R or some GNU softwares?

Thanks,

weiwei
