R help - Oct 2005 - pca in dimension reduction

Hi, there:
I am wondering if anyone here can provide an example using pca doing
dimension reduction for a dataset.
The dataset can be n*q (n>=q or n<=q).

As to dimension reduction, are there other implementations for like ICA,
Isomap, Locally Linear Embedding...

Thanks,

weiwei
