[R] how to GREP out a string like this......THANKS.

[Hon Kit (Stephen) Wong]

Dear ALl,

I hope you could help me out on this simple problem. I have many thousand lines like this:
NM_019397 // Egfl6 // EGF-like-domain, multiple 6 // X F5|X 71.5 cM // 54156

I want to extract the string inside the first // //, in this case is Egf16. 


How do I apply grep function?

Thanks.
