It works correctly as expect

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
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
