Transpose: Wide to Long

rebeccachau — Tue, 22 Jan 2019 06:28:14 GMT

Hi I'm having trouble transposing my wide-format data back to long form. I need to include a variable, TIME, which can be either "1" or "2". The code I am using successfully codes my variables back to the long form, but I can't work out how to get it to add "TIME" as a column as well. Currently each variable in the long form either has a "1" or "2" at the end of the name to denote TIME.

Each ID has a Time "1" and a Time "2", so the long form should look like this:

ID TIME VARIABLE

1234 1 etc

1234 2

4321 1

4321 2

Here is my code:

DATA LONGGEE;

SET WORK.IMPORT5;

TIME=1

ADL=ADL1;

COGTOTSAS=COGTOTSAS1;

FAC=FAC1;

GDS=GDS1;

NHP=NHP1;

PEFITTOTSAS=PEFITTOTSAS1;

SD=SD1;

SOCTOTSAS=SOCTOTSAS1;

OUTPUT;

TIME=2

ADL=ADL2;

COGTOTSAS=COGTOTSAS2;

FAC=FAC2;

GDS=GDS2;

NHP=NHP2;

PEFITTOTSAS=PEFITTOTSAS2;

SD=SD2;

SOCTOTSAS=SOCTOTSAS2;

OUTPUT;

KEEP Obs _Imputation_ ID ADL COGTOTSAS FAC GDS NHP PEFITTOTSAS SD SOCTOTSAS TIME;

RUN;

Thank you!

Are you sure? Your code looks correct, can you post your log and output?

Your KEEP statement should be dropping all your 1/2 variables.

you need to add a semicolon after

TIME=1;

Cripes! Thanks so much.
