Here’s how to use ranks() function.
Description:
Get the rankings of members of sequence A.(x).
Syntax:
|
A.ranks(x) |
Equivalent to A. (x).ranks() |
Note:
The function computes expression x over each member of sequence A to return the rankings of members of sequence A.(x), which by default is sorted in ascending order.
Options:
|
@z |
Return a ranking according to members sorted in descending order (in ascending order by default). Here “z” is in lowercase. |
|
@i |
Deduplicate sequence A.(x) before getting the rankings. |
|
@s |
Perform average operation for each of the duplicate ranking and return the result, which could contain non-integers. Take the sequence [3,2,6,6,9] for example, a default ranking is [2,1,3,3,5]; but with @s option, the ranking becomes [2.0,1.0,(3+4)/2,(3+4)/2,5.0] after we get averages for the two duplicates. |
Parameters:
|
x |
An expression according to which sequence A is computed |
|
A |
A sequence |
Return value:
The rankings of members of sequence A.(x).
Example:
|
|
A |
|
|
1 |
=demo.query("select * from SCORES where SUBJECT='English'") |
|
|
2 |
=A1.ranks(SCORE) |
[7,9,13,1,17,5,13,19,3,25,11,21,23,25,7,9,13,1,17,5,13,19,3,25,11,21,23,25];Rank members in ascending order |
|
3 |
=A1.ranks@z(SCORE) |
[21,19,13,27,11,23,13,9,25,1,17,7,5,1,21,19,13,27,11,23,13,9,25,1,17,7,5,1];Rank members in descending order |
|
4 |
=A1.ranks@i(SCORE) |
[4,5,7,1,8,3,7,9,2,12,6,10,11,12,4,5,7,1,8,3,7,9,2,12,6,10,11,12]; rankings with duplicates removed |
|
5 |
=A1.(SCORE).ranks() |
Same requirement as that in A2 |
|
6 |
=A1.ranks@s(SCORE) |
[21.0,10.0,20.0,2.0,6.0,22.0,26.0,8.0,14.0,9.0,12.0,5.0,15.0,19.0,4.0,11.0,13.0,1.0,28.0,24.0,25.0,16.0,17.0,23.0,27.0,7.0,18.0,3.0]; get averages for duplicate rankings and then return the final result |

Description:
Compute the ranking of each member in a sequence.
Syntax:
A.ranks()
Note:
The function obtains the ranking of each member in sequence A and returns a sequence composed of rankings of the members, which by default are sorted in ascending order.
Parameters：
|
A |
A sequence |
Options:
|
@z |
Return a ranking according to members sorted in descending order. Here “z” is in lowercase. |
|
@i |
Deduplicate sequence A before getting the rankings. |
|
@s |
Perform average operation for each of the duplicate ranking and return the result, which could contain non-integers. Take the sequence [3,2,6,6,9] for example, a default ranking is [2,1,3,3,5]; but with @s option, the ranking becomes [2.0,1.0,(3+4)/2,(3+4)/2,5.0] after we get averages for the two duplicates. |
Return value:
An integer sequence composed of rankings of sequence A’s members
Example:
|
|
A |
|
|
1 |
=[2,1,3,4,8,5,2,0] |
|
|
2 |
=A1.ranks() |
[3,2,5,6,8,7,3,1]; rank members in ascending order |
|
3 |
=A1.ranks@z() |
[5,7,4,3,1,2,5,8]; rank members in descending order |
|
4 |
=A1.ranks@i() |
[3,2,4,5,7,6,3,1]; rankings with duplicates removed |
|
5 |
=A1.ranks@s() |
[3.5,2.0,5.0,6.0,8.0,7.0,3.5,1.0] ; get averages for duplicate rankings and then return the final result |
