Hello, 

 

I am currently working on a data file called work.import. 

 

I need some help. I have a column that I created from timestamp called hOUR_PART 

It basically has different numbers in it reflecting time hours.. e.g. 12, 10, 22 etc. 

I wanted to have values in this column to reflect the following 

any numbers between 0-10 should be AM or 1 

Any numbers between 10-12 (should be morning or 2) 

Any numbers between 12-0 (should be evening or 3) 

 

So Basically I want 1, 2 or 3 to appear instead of the different hours in the column. How would i achieve this?

Just as an FYI in SAS this is not called labels (I believe that's the SPSS terminology?)

This would be recoding the data or applying a format. Labels apply to variable names

 

Note that your intervals overlap in your description so you may need to modify the ranges in your code. 

A basic way of doing this is IF/THEN statements, see below:

 

Assumes your input data set is HAVE, the output data set is WANT and that your variable is named HOUR_PART.

EDIT: for some reason I assumed you had time values but you have hours already. Modified code to correct for this.

 

data want;
set have;

if hour_part in (0:9) then day_code = 1;
else if hour_part in (10:12) then day_code=2;
else if hour_part in (13:23) then day_code = 3;

run;

You want custom formats.

 

proc format;
    value hour 0-10 = '1' 11-12 = '2' 13-23='3';
run;
data want;
    set have;
    format hour_part hour.;
run;

As pointed out by @Reeza your time intervals overlap, I have removed the overlap. If you don't like the way I removed the overlap, it's easy for you to modify.
