I don't have enough RAM for this problem, so I need a work around.  This is
what I want to do:

y<- sample(2^32, 100000, replace=FALSE)

but my machine won't let me do that.  so I now do this:

x<- seq(1,2^32, by=100)
y<- sample(x, 100000, replace=FALSE)

this works fine, but by selecting every 100th item, it introduces a
systematicity that may be problematic.

I've tried this:
x<- seq(1,2^32, by=sample(1:200, 1))

but that yields some unpredictable behavior

so, any suggestions?

Thank you kindly,

Matthew
