Today, I would like to share with you the relevant knowledge points about how to use the rank function in R language. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

The rank function is the subscript that returns the "order" of the original data sorted from smallest to largest.

Example understanding: vector ori

> ori rank (ori) [1] 2 3 1 4 5 6 9 7 8

The order of the original vector elements is 2, 3, 1, 4, 5, 5, 6, 9, 7, 8, 4, 5, 7, 8, 8, 8, 8, 4, 5, 5, 7, 8, 9.

Therefore, it is understood that the rank result is that the first element (2) will appear in the second position after reordering, while the second element (3) will appear in the third place, and so on.

An element of the same size appears, and the corresponding position may be the sum of the positions of the two elements divided by 2

For example:

> ori rank (ori) [1] 2.0 3.0 1.0 4.5 6.0 9.0 7.5 and above are all the contents of this article entitled "how to use rank functions in R language". Thank you for reading!
