[R] how to call rbind using arguments from a list

[Rolf Turner]

I *think* you want:

    ZC <- do.call(rbind,lapply(a,get))

But why do you make "a" a *list* of names rather than a vector of names? 
Generally one uses lists to hold "complicated" structures.
A sequence of character scalars is best stored in an atomic vector.

cheers,

P. S.  Thank you for providing a reproducible example! :-)
