mpi.bcast.Robj and mpi.bcast.Robj2slave are used to move
a general R object around among master and all slaves.
mpi.bcast.Robj(obj = NULL, rank = 0, comm = 1)
mpi.bcast.Robj2slave(obj, comm = 1, all = FALSE)
mpi.bcast.Rfun2slave(comm = 1)
mpi.bcast.data2slave(obj, comm = 1, buffunit = 100)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. mpi.bcast.data2slave
transmits a double vector or a matrix to slaves and returns no value.

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.data2slave transfers data (a double vector or a matrix)
natively without (un)serilization. It should be used with a huge vector or matrix.
It results less memory usage and faster transmission. Notice that data with
missing values (NA) are allowed.
