[R] Random Numbers

Actually this applies not just to random numbers, but...

Suppose I type:
   x <- rnorm(30, 4, 1.5)
to get some 30 random normal numbers with mean 4 and standard deviation

Is there anyway to "re-trace" x?  i.e. am I able to find out what the mean
and standard deviation for x is?

More generally, suppose I generated some random numbers using a particular
distribution.  Can I find out the parameters of the distribution on these
random numbers?
