[R] Graph and function

[Petr Pikal]

Hi

well I am a bit puzzled

> a<-0.2 
>   t<-rexp(1,a)
>    xn<-rpois(1,t)
> B<-(xn+1)/(1+a)   

so B has nothing to do with n 

> b<-mean(x)
> BE<-(1+xn)*b/(1+b)

so as Be
you can use
n <- 1:100
and n as an input vector for some vectorized function but I wonder 
where to put such vector in your pieces of code?
