Hi-

	One question about "random number generation": AFAIK, true random number generation has to receive random input from the "outside." For instance, when you generate GnuPG or PGP keys for encryption, you have to type something on the keyboard.
	With all the other stuff I've seen that purports to generate random numbers, real randomo is no being generated, right?
	Shoudn't R have some function similar to the above mentioned one that exists in PGP or GNuPG?

	TIA
	Regs,
	Henry
