Thanks. That works!
min() function didn't vectorized but "abs( )", "pmin" or "+ /-" did.

integrate() want a vectorized function, one such that length(f(x))==length(x).
Use pmin or pmax instead of min or max.

Hi All,
Can any one help to explain why min and max function couldn't work in the
integrate function directly.
For example, if issue following into R:
integrand <- function(x) {min(1-x, x^2)}
integrate(integrand, lower

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

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.

Hello,
I have some trouble in terms of using integrate function in R.
f1 is a function of p and x where x is supposed to be a vector. (See
the
code).
Then I want to write function f2 which is a function of the vector
x after I integrate out p.
Can
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.
