[R-br] benchmarking

[Leonard de Assis]

Legal,
vou ver se rodo nas 3 máquinas que tenho comigo:

1. Macbook pro 3 gb RAM osx snow leopard core 2 duo
2. core i5 2a geração, 8 gb ram (Linux + windows)
3. core i5 2a geração, 6 gb ram (linux + windows 7 64)

todos com R 64 2.13.1

tenho boa diversão no fds
