r - for loop returns all zeroes when segmenting a beta distribution
0
I am trying to segment a beta distribution, but the for loop returns a vector of zeroes:
my_vector <- vector("numeric", 11L)
prob <- seq(from = 0.0, to = 1, by = 0.1)
for (i in prob ) {
my_vector[i] <- dbeta(i, shape1=7, shape2=2)
}
my_vector
[1] 0 0 0 0 0 0 0 0 0 0 0
r for-loop

my_vector <- dbeta(prob, shape1=7, shape2=2)You can not indexing with doubles (my_vector[i])! e.g.my_vector[0.1]

If you want to do it using the for loop, you may do it like this:
my_vector <- vector("numeric", 0)
prob <- seq(from = 0.0, to = 1, by = 0.1)
for (i in prob) {
my_vector <- c(my_vector, dbeta(i, shape1=7, shape2=2))
}
my_vector
