[R] Random Number Testing

[dcum007@ec.auckland.ac.nz]

Thank you to all who helped me with my previous question regarding random 
numbers. I have read up on the subject and found a whole new interesting world. 
I found some code wich I translated into java for my project and now have a few 
pseudorandom number generators. I was wondering if R had any inbuilt tests for 
randomness (a birthday-spacings, serial correlation...) or would I need to 
write my own (in either R or java)?
Thanks to all
