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

For example, if issue following into R:

Hi All,

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

Thank you so much for your help Berend.
I did not see that my code had a typo and it was thus wrongly written ( I
overlooked the i that was supposed to be actually 1)
instead of for (q in *1*:length(comb1$ID))
I had it as for (q in *i*:length(comb1$ID))
It works correctly as

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

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 some one give me some help? Many thanks!

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)

e2-function(a) integrate(function(x) x,lower=0,upper=a)$value
integrate(e2,lower=0, upper=0.5)$value
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.
