[R] error message: .Random.seed is not an integer vector but

[Jim Bouldin]

Thanks much Ted.  I actually had just tried what you suggest here before
you posted, and resolved the problem.  Thanks also for the other tips.  I
wrote x = as.vector(c(1:12)) because I thought that the mode of x might be
the problem, the error message pointing to .Random.seed notwithstanding.

On a related note, I did a brief test a couple weeks back where I ran a
million random samples of 3 from the vector 1:12 and compared the mean
against the known mean.  It was off by 1 percent, which indicated that the
RNG was biased more than I'd have thought.  Comments?
