[R] qbinom

[jaybell]

sorry, I repost the question again  

a=c(0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9) 
b=c(0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1) 
cor(a,b)= -1 

pa=qbinom(a, 1, 0.5) 
pb=qbinom(b, 1, 0.5) 
cor(pa,pb)=-0.8

but when  
pa=qbinom(a,10,0.5)
pb=qbinom(b,10,0.5)

cor(pa,pb) becomes -1 again
