DVD writer problem
I have an NEC DVD-RW ND2500A (that's not the label I bought it under, but that's what it really is.) It's supposed to read/write CDs, DVDs, DVD+Rs, and DVD-Rs.

R strange behaviour when building huge concatenation
Hello I'm using some R code in order to use the model BG-NBD implementation I'm using Java and I call R by using RCaller.
