Hi,

I would greatly appreciate if somone could help me with the SAS code to count number of observations/records under each column variable in the attached table(Table 1).

My task is I want to count the number of pop cont and can cont under each of the variables lung loat lsquam ladeno.

I know that probably I need to use proc means or proc freq to do the counts but I am not sure about the right code.

Any help,please? Thanks in advance.

My task is I want to count the number of pop cont and can cont under each of the variables lung loat lsquam ladeno.

As I look at the output in your attached file, it seems as if you have programmed SAS to do this counting. So I'm not sure what you are asking.

This is overkill for what you want but definitely gives you that.

Otherwise a PROC MEANS is likley all you need, assuming numeric variables - results are stored in the 'want' data set. The solution above works regardless of types.

```
proc means data=sashelp.class N NMISS;
ods output summary=want;
run;
proc print data=want;
run;
```

You may get a better answer if you provide:

1) a small example data set as data step code.

2) What you expect for the result given that example data.

The example should be big enough to demonstrate some difference in the resulting count but small enough you can create the output by hand to show the desired result and layout.

Here's something similar to what I think you are wanting, a single table with the counts per column heading.

data example; input var1 $ var2 $ var3 $; datalines; A B A A A B A B B A B A B B B B A A B B A ; data temp; set example; array v var1 var2 var3; do i=1 to dim(v); name = vname(v[i]); value = v[i]; output; end; run; proc tabulate data=temp; class name value; table value,name ; run;

Thank you. I will provide a small dataset then.
