proc freq doesn't work?

[deleted_user]

hi,can somebody help me?thanks!
there're many teachers working for different department,most of them will teach in more than one department.I want to count frequencies of each teacher for each year and each school,and output to data set.
sample:
department year teacher
econ 2002 Samon
econ 2003 Samon
manag 2003 Stephen
manag 2003 Sissi
Chem 2002 Sissi
Chem 2003 Samon
Math 2003 Stephen
Math 2004 Laura
Eng 2002 Laura
Eng 2003 Stephen
My program is :
Proc freq data=a;
table teacher*(department year)/out=freqteacher;
run;

Look at the BY statement - you will need to sort your data on the BY variable list.

Actually, I do not know exactly what is your error:
Here are sample code:

data a;
input department $ year teacher$;
datalines;
econ 2002 Samon
econ 2003 Samon
manag 2003 Stephen
manag 2003 Sissi
Chem 2002 Sissi
Chem 2003 Samon
Math 2003 Stephen
Math 2004 Laura
Eng 2002 Laura
Eng 2003 Stephen
;
run;

Proc freq data=a;
table teacher / out=freqteacher;
table teacher*department /out=freqteacher_bydepart;
table teacher*year /out=freqteacher_byyear;
table teacher*department*year /out=freqteacher_bydepart_byyear;
run;
