[R] outlier detection

[Weiwei Shi]

Thanks. 
I knew rf based on proximity can detect the outlier but when the data
size goes to 1 million and the features go around 200, I guess I
probably do not have enough memory to proceed. Do u have some
experience of outlier detection in this kind of data size?

regards,

weiwei
