SAS code trying to delete all rows not matching an entry

Moviefan04 — Wed, 19 Jul 2017 18:55:02 GMT

I am working in SAS 9.4. I have a data set and one of the variables is called 'state'. I need to remove all rows in which the 'state' variable is not equal to 'Alaska'. I also need to combine three other variables (month, day, and year) to create a new variable called EruptionDate and then drop those other 3 variables. The final thing that I can't figure out is how to only display the eruptions occuring after the year 2005. I am quite new to SAS and programming in general and this is what I have so far, but it's not working:

DATA Alsaka;

SET Work.earthquake;

IF State = Alaska

THEN EruptionDate = Month, Day, Year

ELSE REMOVE row;

DROP Month;

DROP Day;

DROP Year;

RUN;

PROC PRINT Data= Alaska;

WHERE year GT 2005;

RUN;

Thanks for any help.

There are errors in your code. Can you post a few observations of your data?

Depends upon what values you have for Month, Day and Year. You may be able to use something like:

DATA Alaska (drop=Month Day Year);
  SET Work.earthquake;
  format EruptionDate date9.;
  IF State = 'Alaska' THEN do;
    EruptionDate = mdy(Month, Day, Year);
    output;
  end;
RUN;
PROC PRINT Data= Alaska;
 WHERE year(EruptionDate) GT 2005;
RUN;

I made a few adjustments to tailor it to get my desired result but your post helped a lot. Thank you!
