How to find the smallest values of the vectors sequentially
Suppose I have a vector x and I would like to find the smallest values of this vector. Then, I would like to return a new x without the selected element and then extract the smallest value from the remaining values and so on.
For example,
x <- c(3,4,2,1,6,10.14,100,7)
I would like to extract the smallest value of this vector. In this example, the smallest value is 1. Then, I would like to return x without 1.
x_1 <- c(3,4,2,6,10.14,100,7)
After that, I need to select the smallest value from x_1 and then get x_2 and so on.
How can I do this automatically in R?

We can create a function remove_small_vec which removes the lowest value from the vector. We then run a while loop which runs till length of vector is >= 1.
remove_small_vec <- function(vec) {
vec[vec != min(vec)]
}
list_vec <- list()
while (length(x) >= 1) {
list_vec <- c(list_vec, list(x))
x <- remove_small_vec(x)
}
list_vec
#[[1]]
#[1] 3.00 4.00 2.00 1.00 6.00 10.14 100.00 7.00
#[[2]]
#[1] 3.00 4.00 2.00 6.00 10.14 100.00 7.00
#[[3]]
#[1] 3.00 4.00 6.00 10.14 100.00 7.00
#[[4]]
#[1] 4.00 6.00 10.14 100.00 7.00
#[[5]]
#[1] 6.00 10.14 100.00 7.00
#[[6]]
#[1] 10.14 100.00 7.00
#[[7]]
#[1] 10.14 100.00
#[[8]]
#[1] 100
This returns a list of vectors of length same as x with one element removed in each list element.

x <- c(3,4,2,1,6,10.14,100,7)
