Hi All,

Assuming your data are sorted:

proc transpose data=have prefix='addr' out=want;

by first_name last_name;

var addr;

run;

Hi,

Yes, I tried this. But I need 6 variables for address.

In the example, there are only 4 occurance; therefore, addr5, addr6 should be blank.

You need to provide better sample data and sample required output. Please also include some more details in your question.

Sorry, I will try to be more clear.

I have input data as shown below. I need to group based on first and last name and populate address(s) across [horizontal] like shown below [max 6 address variables each].

Input:

First name	Last name	New Addr	Old Addr
Tony	Greg	apt#1276	apt#909
Tony	Greg	DRAGRAM	DRAGRAM
Tony	Greg	TUCSON AZ 85705	TUCSON AZ 85705
Tony	Greg	USA	USA
Ricky	Pointing	apt#711	300
Ricky	Pointing	Jugle ave East	BOYLSTON AVE E
Ricky	Pointing	PHOENIX	SEATTLE
Ricky	Pointing	AZ 85123	WA 98102
Ricky	Pointing	USA	USA
arjuna	ranatunga	100 MAIN ST	apt#1276
arjuna	ranatunga	PO BOX 1022	100 Islington rd west
arjuna	ranatunga	SEATTLE WA 98104	Seattle
arjuna	ranatunga	USA	WA 93102
arjuna	ranatunga	USA

Output:

The simplest way is using proc means + idgroup .

Or MERGE skill . Me ,Matt, Arthur.T have talked about at this paper .

http://support.sas.com/resources/papers/proceedings15/2785-2015.pdf

Code: Program

data have;
infile cards truncover expandtabs;
input (Firstname Lastname NewAddr OldAddr) (: $40.);
cards;
Tony Greg apt#1276 apt#909
Tony Greg DRAGRAM DRAGRAM
Tony Greg TUCSON AZ 85705 TUCSON AZ 85705
Tony Greg USA USA
Ricky Pointing apt#711 300
Ricky Pointing Jugle ave East BOYLSTON AVE E
Ricky Pointing PHOENIX SEATTLE
Ricky Pointing AZ 85123 WA 98102
Ricky Pointing USA USA
arjuna ranatunga 100 MAIN ST apt#1276

;
run;
proc sql;
 select max(n) into : n
  from (select count(*) as n from have group by Firstname,Lastname);
quit;
proc summary data=have nway;
class Firstname Lastname;
output out=want idgroup(out[&n] (NewAddr OldAddr)=);
run;

Hi Xia,

Thank you. I used Transpose + merge and it worked as expected.

PROC TRANSPOSE will create as many variables are are actually needed by your data. If you are only getting four address variables, it's because that is as many as is required to transpose your data. You can easily convert that to six variables with two blank ones. Operating on the output of the PROC TRANSPOSE:

data want;

set want;

length addr5 addr6 $ 100;

run;

Pick whatever length you feel is appropriate for the extra two variables.

Hi Astounding,

But it is not always that first 4 records will have address.

There is a case where address is only one record i.e. addr1 has entire data and addr2 thru addr6 should be space.

There is a case where address is in 6 records i.e. addr1 thru addr6 has value [complete address].
