can't integrate in loop
Thats not a very precise question. I'll try anyway.. - if you use c, you need to separate the values by commas - i think you mean seq(1,100,0.1), otherwise x only has one value - function sen is not defined - If you call int(1), upper will be 1, not x[i] - why are you making a function and calling it instead of just : int1[i] <- integrate(H, lower = 0, upper = x[i]) ? - looking at ?integral, you may rather want integral(..)$value

Hi guys!
I have to compute something and i don't know what i'm doing wrong. my code
is a bit complex, but imagine that is something like this:
a = c(1 2 3 4)
ia = length(a)
x = seq(1,100,length=0.1)
ib = length(x)
for(j in 1:ia) {
H = function(x) {sen(x) + a[j]}
for(i in 1:ib) {
int = function(x) { integrate(H, lower = 0, upper = x[i])}
int1[i] = int(1)
}
end
int1 = unlist(int1)
ss[j] = sum(int1)
}
end
if i try this code without the for loop it's ok, but when i put the cycle
on, i get all sort of errors...
Thank you for your help :)
