Why are you using 'i' in both of the 'for' loops? The value in the
first is overwritten by the second and you will not get the correct
answer.
r <- rnorm(1000,0,1)
caminho <- c(1 , 3.2 , 1.2 , 3, 2, 1, 4, 5)
p2<-function(r){
gama=0
for(i in 1:1000){
c=caminho[[4]]
for(i in 1:caminho[[3]]+1) {
c=c+caminho[[i+3]]*((r[i])^(i-1))
d=(abs(c))*exp(-(x^2/2))}
gama=gama + ( d/(h(r[i]))
)
}
return(gama)
}
e3<-p2(r)
Also why are you using '[[' to access the vector caminho? You sample
program is not complete since 'x' is not defined. Also do you mean
'1:caminho[3]+1' or '1:(caminho[3]+1)' in the second for loop. They
will give you different answers.
So what is the problem you are trying to solve?
