Exeperts,
I have huge dataset and I want to reorder my row number 1-6.how do I order when I don't have other variable to group.
here is the sample SAS program:
data want;
set sashelp.class;
rownum=_n_;
newvalue=mod(rownum,2);
run;
Here is the expected output:
Name | Sex | Age | Height | Weight | rownum | newvalue |
Alfred | M | 14 | 69.0 | 112.5 | 1 | 1 |
Alice | F | 13 | 56.5 | 84.0 | 2 | 2 |
Barbara | F | 13 | 65.3 | 98.0 | 3 | 3 |
Carol | F | 14 | 62.8 | 102.5 | 4 | 4 |
Henry | M | 14 | 63.5 | 102.5 | 5 | 5 |
James | M | 12 | 57.3 | 83.0 | 6 | 6 |
Jane | F | 12 | 59.8 | 84.5 | 7 | 1 |
Janet | F | 15 | 62.5 | 112.5 | 8 | 2 |
Jeffrey | M | 13 | 62.5 | 84.0 | 9 | 3 |
John | M | 12 | 59.0 | 99.5 | 10 | 4 |
Joyce | F | 11 | 51.3 | 50.5 | 11 | 5 |
Judy | F | 14 | 64.3 | 90.0 | 12 | 6 |
Louise | F | 12 | 56.3 | 77.0 | 13 | 1 |
Mary | F | 15 | 66.5 | 112.0 | 14 | 2 |
Philip | M | 16 | 72.0 | 150.0 | 15 | 3 |
Robert | M | 12 | 64.8 | 128.0 | 16 | 4 |
Ronald | M | 15 | 67.0 | 133.0 | 17 | 5 |
Thomas | M | 11 | 57.5 | 85.0 | 18 | 6 |
William | M | 15 | 66.5 | 112.0 | 19 | 1 |
Appreciate your help.
thanks,
Use the MOD() function.
Reeza,
I am using MOD() function but I am getting 1 and 0.
if you don't mind could you please add your code to example above.
thanks,
Post what you've tried and I'm happy to help.
When I this:
data want;
set sashelp.class;
rownum=_n_;
newvalue=mod(rownum,2);
run;
I got this one.
Name | Sex | Age | Height | Weight | rownum | newvalue |
Alfred | M | 14 | 69.0 | 112.5 | 1 | 1 |
Alice | F | 13 | 56.5 | 84.0 | 2 | 0 |
Barbara | F | 13 | 65.3 | 98.0 | 3 | 1 |
Carol | F | 14 | 62.8 | 102.5 | 4 | 0 |
Henry | M | 14 | 63.5 | 102.5 | 5 | 1 |
James | M | 12 | 57.3 | 83.0 | 6 | 0 |
Jane | F | 12 | 59.8 | 84.5 | 7 | 1 |
Janet | F | 15 | 62.5 | 112.5 | 8 | 0 |
Jeffrey | M | 13 | 62.5 | 84.0 | 9 | 1 |

William | M | 15 | 66.5 | 112.0 | 19 | 1 |
Why are you using 2 in the MOD() function?
I am trying to divide by 2.
Reeza,
data want;
set sashelp.class;
rownum=_n_;
newvalue=mod(rownum,6);
run;
Name | Sex | Age | Height | Weight | rownum | newvalue |
Alfred | M | 14 | 69.0 | 112.5 | 1 | 1 |
Alice | F | 13 | 56.5 | 84.0 | 2 | 2 |
Barbara | F | 13 | 65.3 | 98.0 | 3 | 3 |
Carol | F | 14 | 62.8 | 102.5 | 4 | 4 |
Henry | M | 14 | 63.5 | 102.5 | 5 | 5 |
James | M | 12 | 57.3 | 83.0 | 6 | 0 |
Jane | F | 12 | 59.8 | 84.5 | 7 | 1 |
Janet | F | 15 | 62.5 | 112.5 | 8 | 2 |
Jeffrey | M | 13 | 62.5 | 84.0 | 9 | 3 |
John | M | 12 | 59.0 | 99.5 | 10 | 4 |
Joyce | F | 11 | 51.3 | 50.5 | 11 | 5 |
Judy | F | 14 | 64.3 | 90.0 | 12 | 0 |
Louise | F | 12 | 56.3 | 77.0 | 13 | 1 |
Mary | F | 15 | 66.5 | 112.0 | 14 | 2 |
Philip | M | 16 | 72.0 | 150.0 | 15 | 3 |
Robert | M | 12 | 64.8 | 128.0 | 16 | 4 |
Ronald | M | 15 | 67.0 | 133.0 | 17 | 5 |
Thomas | M | 11 | 57.5 | 85.0 | 18 | 0 |
William | M | 15 | 66.5 | 112.0 | 19 | 1 |
So all you need now is to change the 0's to 6's.
Or you can muck around a bit more with the MOD function which ends up something like:
x= mod(i-1, 6)+1;
