mpi.bcast.Robj(obj = NULL, rank = 0, comm = 1)
mpi.bcast.Robj2slave(obj, comm = 1, all = FALSE)
mpi.bcast.Rfun2slave(comm = 1)

`obj`	an R object to be transmitted from the sender
`rank`	the sender.
`comm`	a communicator number.
`all`	a logical. If TRUE, all R objects on master are transmitted to slaves.

mpi.bcast.Robj is an extension of mpi.bcast for moving a general R object around from a sender to everyone. mpi.bcast.Robj2slave does an R object transmission from master to all slaves unless all=TRUE in which case, all master's objects with the global enviroment are transmitted to all slavers.

mpi.bcast.Robj returns no value for the sender and the transmitted one for others. mpi.bcast.Robj2slave returns no value for the master and the transmitted R object along its name on slaves. mpi.bcast.Rfun2slave transmits all master's functions to slaves and returns no value.
