[R] SOM random seed

[Jonck van der Kogel]

Hi all,
I have a question about the SOM routine. You can either supply the 
initial representatives for the lattice yourself or else they are 
chosen randomly from the dataset. Is it possible to pass the 
random-seed as an argument somehow, when choosing the random 
initialisation of the lattice?
As it is now, each time I run a SOM on a dataset with the same settings 
the resulting SOM will still be slightly different due to the random 
initialisation.
Thanks for any help, Jonck
