set.seed(x)
I asked a similar question earlier in the year, http://r.789695.n4.nabble.com/How-to-stop-set-seed-besides-exiting-out-of-R-td4661717.html I liked this solution from William,
rm(list=".Random.seed", envir=globalenv())

Hello, If I use set.seed(x) to set a seed for the random number generator, how can I undo that to revert a random output every time I run my code?
If you remove .Random.seed, then the next time a seed is needed it will be generated from the system clock, so it will appear random.
Also, in recent versions of R (>= 3.0.0 I believe) set.seed(NULL) will do the same. MW
