Hi Laila, Here is a suggestion: res <- integrate(dnorm, -1.96, 1.96) res # 0.9500042 with absolute error < 1.0e-11 res[[1]] # [1] 0.9500042 res$value # [1] 0.9500042 HTH, Jorge On Sun, Nov 1, 2009 at 3:02 PM, Laila Alkhalfan <> wrote: > Hi > Can we get the result of an intigration without

[R] intigrate function and absolute error

2009-11-01 Thread Laila Alkhalfan
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
