# If condition

Hi Team,

I have a dataset and did a proc freq of Code*description and i get what is shown below

I want to put OTHER in the description column for those which have a count of 5 or less

I should get like shown below if I did the freq of the dataset

Code  Description Freq Count

000        OTHER               20

I have several hunderds which have count less than 5

I cannot write IF condition for several hunderds in the parent dataset like:

if Description in ("Urinary", "Heart" ,"nose" "head"," hand"," finger"," toes") then do;

Description="Other";

code="000";

end;

run;

Code    Decription     freq count

100       pain                 15

101        urinary            3

102        digestive        33

103        heart              2

104        nerves           55

105        nose              1

107       leg                  45

108       hand                2

109       finger               5

110       toes                 3

Thanks

## Re: If condition

Then use the proc freq output to feed a lookup table so its dynamic and you aren't using an if.

ie

proc freq data=have;

table code*description/out=list_format;

run;

data list_format;

set list_format;

if count<= 5 then do;

new_description='Other';

new_code=999; *so it will sort last;

end;

else do;

new_description=description

new_code=code;

end;

drop count;

run;

proc sort data=have; by code description;

proc sort data=list_fmt; by code description;

data want;

merge have list_fmt;

by code description;

run;

## Re: If condition

if count<5 then description='Other' ?

Or would you like to group all the ones with less than 5 individually together into one 'Other'?

## Re: If condition

Yes. I would like to group all the ones with 5 and less than 5 into one "OTHER"

AND also what you see is not my actual dataset.Its the dataset after I did the freq......

I need to make these changes in my Parent dataset.

I just did a freq to see how many are less than 5!!!

AND I HAVE SEVERAL HUNDREDS OF THOSE WITH LESS THAN 5 Making it difficult for me to use the IF condition

Regards

## Re: If condition

Thanks a lot.

I understood the logic.

So after merging the datasets we consider the new_code and new_description for Proc Freq purpose RIGHT????

Secondly,

When we converted to new_code code which was 001 is getting translated to 1(no leading zeros)

Is there any way i could retain the leading zeros???

Thanks

## Re: If condition

New_code is defined as numeric in the example.

For printing with leading zeros in a report, use z. format.

Otherwise, define it as char instead.
