This looks good, except it is truncated, it should be something like
95chars long, Is your hash column set to 128 or up around there or
larger?

uniform integer RNG 0 to t inclusive
...(n, min, max) it states that
the generated numbers will be min <= x <= max. Note the "<= max"...
How do I generate an x such that the probability of being (the
integer) max is the same as any other integer from min (an integer) to
max-1 (an integer) inclusive... My attempt is:
urand.int <- function(n,t) {
as.integer(runif(n,min=0, max=t+1-.Machine$double.eps))
}
# where I've included the parameter n to help testing...
is floor() "better" than as.integer?
Is this correct? Is the probability of the integer t the same as the
integer 1 or 0 etc... I have done...

Problem compiling 1.2.2 on solaris
I am trying to run the configure for 1.2.2 on an intel solaris 2.7 box
and I get an error for urandom not found.
I cant find anything related to rand, urand, random, rng, or urandom on
my box.
How can I get around this, or where can I get urandom?
