[igraph] stochastic nature of network coordinate generation?

[James T Metz]

Igraph Users,

        I
am using the following function to generate 2D coordinates for a network

        coords
<- layout.fruchterman.reingold(network, weights = E(network)$weight)

        However,
I have noted that when I call this function several times, I get different
coordinates for the same input.  Hence,
there seems to be some kind of stochastic
or random characteristic of this function.

        Is
there a random number seed or some parameter that can be set so that the
same
output coordinates are generated for
the same input every time this function is called?

        Thank
you.

        Regards,
        Jim
