I am wondering if someone could help me out with following problem:
I have written a for loop which generates a random normal distribution  
let us say 1000 times.
When the restriction is met (mean<0.000001), the loop stops, prints  
the mean value and plots a histogram.

for(i in 1:1000) {
	a<-rnorm(1000,0,.2)
	b<-abs(mean(a))
		if(b>.000001) next else {print(b);hist(a);break}}

How to reshape the loop when I want to find at least 5 distibutions  
that meet my restriction and save them (assign) under
names R1....R5.
Could you help me please?

Michael
