[R-sig-Geo] RandomFields: Randomness in realisations of sequential simulation?

[Andre Jung]

Dear all,

I've some general question regarding the implementation of
randomness in RandomFields and sequential simulation.

(1) Is there a difference between running
    krige(nsim = 5, ....)
     and running
    krige(nsim = 1, ....)
     for 5 times?

(2) Does repeating of the simulation with the same random number seed
     (how to keep the seed?) lead to the same realisations? And: how
     random is the path?

(3) Can I fix the parameters (which ones?) to reproduce the same
     realisations a later time?


Another question is: How can I generate an 'e-type' of, let's say 10, 
realisations, and do some post-simulation analysis like defining 
probability to be above or below a certain threshold?


Many thanks in advance!

best,
Andre
