Abstract: An analytic theory of ballistic electron transport in disordered graphene in ``short-and-wide'' geometry is developed. We consider a sample of a large width $W$ and analyze the evolution of the conductance, the shot noise, and the full statistics of the charge transfer with increasing length $L$ both at the Dirac point and at a finite gate voltage. The transfer-matrix approach combined with the disorder perturbation theory and the renormalization group is used. We also discuss the crossover to the diffusive regime and construct a ``phase diagram'' of various transport regimes in graphene.
