• sparmat and sparvec can convert matrices and vectors in compressed format (nrow, ncol, val) or (nIndex, val) into the sparse format [nnz, N]. All data structures are tables.

• Currently the NRPF algorithm does NOT support bus type conversion. This obviously affects convergence for bigger bus systems, but fortunately does not seem to affect the ieee14 and ieee30 bus systems.
• Currently it converges for the ieee14 and ieee30 bus systems, has trouble with ieee57 bus system for a couple of buses and blows up for the ieee118 bus system.
• $N$ bus systems with individual bus numbers $i$ outside the range of natural numbers from $[1, N]$ are currently NOT supported. The ieee300 bus system is one such system.
