[R] Writing point pattern to a file

        I am trying to use the R package 'spatstat' for generating spatial poisson point process graphs. I can create a point pattern using the following commands:

        pp <- rpoispp(.01, win=owin(c(0,100),c(0,100)))

        and also view the resulting graph by:


        But how can I export the generated point pattern to an external file so that I could use it as input for some network simulation programs ? Also, it seems that the generated graph is different on each invocation. Is there a way I could control this randomness, some seed perhaps.

Thanks in advance,
