Or:
a = rpois (100000, 0.1)
b = rpois (100000, 0.15)
table(a>b, a==b, b>a)
And if you look at that output a bit:
table(a<b,a==b )[c(1,3,2)] # for a>b, b>a and a=b .
# 79049 12712 8239 .. since FALSE < TRUE

i have

b = rpois (100000, y)
what is the code to show that a>b, b>a and a=b to show just the
number of
occurances?
occurrences?
at the moment when I type a>b I get a nice long list of true or
false.
As you _should_ when you supply two vectors to a binary operator.
