Subject: [R] intigrate function and absolute error
To: r-help@r-project.org
> Hi
> Can we get the result of an intigration without the absolute error?
> for example
> f1<-function(x1){(1/gamma(alpha))*x1^(alpha-1)*exp(-x1)*log(x1)}
> I1<-integrate(f1, 0, (max(cc)-tau1+(theta2/theta1)*tau1)/theta2)
> I1
> 0.08007414 with absolute error < 7.2e-05
> I need the answer 0.08007414 withou the other part(with absolute error
> <7.2e-05)
> how can we do that?
