使用for循环填充R中的向量

Question

I'm simplifying this question, for clarity.

Say I want to create a vector with a number of elements with the value zero. I then want to use a for-loop to replace every element with its own index number inside the vector.

Can this be done?

K <- 11
p <- rep(0, K + 1)
for (k in 0:K) {
p[k+1] <- .... ?
}

Answer 1

Here's one solution if I understand your expected output:

K <- 11
p <- rep(0, K + 1)
for (k in 0:K) {
  p[k + 1] <- k
}

Which returns:

[1]  0  1  2  3  4  5  6  7  8  9 10 11
