How to pick some paticular year in each country data to concatenate together

[Phil_NZ]

Hi SAS Experts,

Today I want to pick some specific observations in each country in one dataset named "wins_sample" to create a new dataset called "treatment"

I have the dataset wins_sample attached

A quick description of observation of the dataset wins_sample

TYPE	ENAME	    GEOGN	    YEAR	acc_pay	ACC_PAY_TUR	    ACC_STA
134495	DYCASA 'B'	ARGENTINA	1994	7445	.	            Local standards
134495	DYCASA 'B'	ARGENTINA	1995	10099	8.7216142271	
134495	DYCASA 'B'	ARGENTINA	1996	6277	8.0189301417	Local standards
134495	DYCASA 'B'	ARGENTINA	1997	8419	11.732035928	Local standards
134495	DYCASA 'B'	ARGENTINA	1998	15387	7.5126438713	Local standards


/*type, year, acc_sta geogn: character variables
acc_pay, acc_pay_tur: numeric variables*/

The dataset wins_sample here has 3 countries: Argentina, Australia, and Austria.

For this sample, what I want is to create a dataset named "treatment" that contains all observations which has YEAR from 2001,2002, 2004->2008 (from 2001 to 2008 but not the observations in the year 2003) in GEOGN= "AUSTRALIA" and all observations which has YEAR from 2004,2005, 2007->2011 in GEOGN ="AUSTRIA" 

Many thanks in advance and warm regards.

where
  (geogn = "AUSTRIA" and 2004 le year le 2011 and year ne 2006) or
  (/* add similar for AUSTRALIA */)
;

Hi @Phil_NZ,

If you store the year values in a numeric variable, then you don't need the conversion using the INPUT function as shown below:

data treatment(drop=yr);
set wins_sample;
yr=input(year, ?? 32.);
if  geogn="AUSTRALIA" & yr in (2001:2008) & yr~=2003
  | geogn="AUSTRIA"   & yr in (2004:2011) & yr~=2006
;
run;

Hi @FreelanceReinh 

I am not sure if the highlighted symbol here is "or"

Sorry I am not sure about this symbol from google so I ask.

Because there is a link about operator

https://documentation.sas.com/?cdcId=pgmsascdc&cdcVersion=9.4_3.5&docsetId=lrcon&docsetTarget=p00iah...

And many types of "OR"

Many thanks!

[FreelanceReinh]

Yes, the pipe character (|) is the OR operator (see second row in the table "Logical Operators"). But feel free to use the mnemonics or, and, ne, etc. if you're more familiar with them or if the dependence on the operating environment (see footnotes under the table "Logical Operators") is a concern.

Hi @FreelanceReinh 

What if I want to pick observation in country GEOGN="BRAZIL" and from "1991->1997"( excluding 1993) or "2007 ->2017", can you suggest to me how to fill in the code below?

data control;
set wins.winsorize;
yr=input(year, ?? 32.);
if geogn="UNITEDS"        & yr in (1999:2017)
   |geogn="BRAZIL"        & yr in (1991:1997) & yr~=1993 /*and what else*/
;
run;

Can we do:

geogn="BRAZIL"        & ((yr in (1991:1997) & yr~=1993)or yr in (2007:2017))

Warm regards.

Yes, this is correct. The parentheses which I've highlighted in blue below are redundant, but they may help to understand the logic. I would insert a blank between ")" and "or" for better readability.

geogn="BRAZIL" & ((yr in (1991:1997) & yr~=1993) or yr in (2007:2017))

If you're unsure about a logical condition like this, you can also create a small test dataset with the relevant variables (geogn, yr), let yr run from, say, 1990 to 2020 (DO loop), apply the IF condition and check the result.

data treatment;
		set have.wins_sample ;
		where (GEOGN="ARGENTINA") or
              (YEAR in ('2001','2002','2004','2005', '2006','2007','2008') and GEOGN= "AUSTRALIA") or
              (YEAR in ('2004','2005','2007','2008','2009','2010','2011')  and GEOGN= "AUSTRIA");
run;

Did you try this?
