##### Class "Simulation"

In an object of type Simulation data can be simulated in any distribution and size.

##### Note

Changing distribution, seed, runs or samplesize deletes possibly simulated data, as it would not fit to the new parameters.

##### Objects from the Class

Objects can be created by calls of the form Simulation(filename, runs, samplesize, seed, distribution). A Simulation-object includes a filename, the number of runs, the size of the sample, the seed and the distribution of the random numbers. The slot Data stays empty until the method simulate has been used.

##### Extends

##### Examples
N=Norm() # N is a standard normal distribution.
S=Simulation(filename="xyz",runs=10,samplesize=3,seed=setRNG(),distribution=N)
Data(S) # no data yet
simulate(S)
Data(S) # now there are random numbers
Data(S) # the same data as before because the seed has not changed
seed(S)=setRNG()
simulate(S)
Data(S) # different data
savedata(S) # saves the object in the directory of R...
Data(S) # ...without the data - use simulate to return it!
