summing on character variables

[r4321]

Hello everyone, 

I'm trying to sum on character variables and I'm trying to think about the best way to approach this goal. Let me sketch the rough structure of my data. 

ID       Country 

1      United States 

1      United States

1      France 

1      Canada

2      South Africa

2      Japan 

2      Japan 

2      Japan

3      United States

3      Canada

3      Canada

3      Canada

I want the output to show me how many of each country appears for each ID, like so :

ID   Country       numberofoccurence

1 United States    2

1 Canada            1 

1 France             1

2 South Africa     1

2 Japan              3

3 United States  1 

3 Canada           3 

How can I accomplish this? 

As always, thanks for your help.

There are multiple SAS Proc's you could use for this task.

I'd probably go for Proc SQL with a count(*) in the Select statement and a Group By ID, Country

Nice and easy with PROC SQL:

proc sql;

create table want as

select ID, Country, count(*) as numberofoccurence

from have group by ID, Country;

[Miracle]

Or this? proc freq data=have noprint; tables id*country / out=want(drop=percent rename=count=numberofoccurence); run;

You aren't summing you're counting the number of occurrences by a categorical variable. I'm only clarifying the term so that you can search for valid solutions. Key word searches requires the correct key words and are primarily designed for English speakers.
