Rmpi: send a function to a slave from master and let it run?

Hello All,

Can send different functions  to different slaves from master and let each 
slave run itself function using Rmpi? From the Rmpi version 0.4.2, I know 
how to send a function to all slaves and let slave run the function.  
mpi.send.Robj may send a function to a slave, but how let the salve run the 
function?


Thanks.
