[R] copying R objects in C

[Csardi Gabor]

Dear R Users,

do you know a way to copy an R object using C code? I know that
there is a copyMatrix and also a copyVector function. There is
also something called copyListMatrix, what is this good for? Is
there anything for copying a list (of course deep copy is
needed)? 

Thank you for your help,
Gabor
