Hi All,
Can any one help to explain why min and max function couldn't work in the

For example, if issue following into R:

Apologies for the lengthy code.
I tried a simple (and shorter) piece of code (pasted below) and it still
gives me the same error for last few rows. Is this a bug or am I doing
something totally wrong? Could anyone please provide some help/pointers ?
PS. beta0 was fixed to 0.001 in the previous c

Hi,
I am using the integrate function in some simulations in R (tried ver 2.12
and 2.15). The problem I have is that the last few rows do not integrate
correctly. I have pasted the code I used.
The column named "integral" shows the output from the integrate function.
The last few rows have no integ

Thank you very much for your reply!
It is not an assignment.
What I want to do is what we often do. If we have a bivariate function of x
and p,
I first fix x and integrate out p. Then the resultant function is only in
terms of x.
Here f1 is a bivariate function of x and p.
> f1 <- function (p,x

Change e2 to the following and it works
e2 <- function(a) a^2/2
The reason it doesn't is that e2 must be able to handle vector inputs
correctly. Your original function does not do this.
from ?integrate
f - an R function taking a numeric first argument and returning a
numeric vector of the sam
This is my code , when i run it ,error happed . can you tell me what's the
reason and modify it ?thank you very much !! the error is "evaluation of
function gave a result of wrong length"
e2<-function(a) integrate(function(x) x,lower=0,upper=a)$value
integrate(e2,lower=0, upper=0.5)$value
?integrate, it is in the documentation
