Delete columns in Proc Tabulate output

ebowen — Thu, 13 Dec 2012 17:24:48 GMT

I'm using Proc Tabulate to break out the wages and percentages of people in my state vs. people out of state based on their education level. I've managed to output what I want, but I really don't need the data from people out of state, so I would like to eliminate that from the output. Essentially, I'm trying to delete a column from the output based on the value of the data in the class variable. Here's my tabulate procedure as it stands:

PROC TABULATE DATA=employment;

class Year InState Degree;

var Wage;

table Year='', ALL InState*Degree*(pctn<inState> Wage*mean) /nocellmerge;

RUN;

Is there any way to get rid of the output for just the out of state people based on the value of the InState variable? I've tried using a WHERE clause to limit the data to only in-state people, but that messes up the percentage variable. I am outputting the table via ODS, so if there's a way to eliminate the column from ODS that would work too.

Thanks for your help!

If all else fails, here's the general solution to this type of problem.

1. Create a summary data set from PROC TABULATE, instead of printing.

2. Subset the summary data set to contain just the values that should go into the report.

3. Use the modified summary data set as the input to a second PROC TABULATE that actually prints the report.

The final PROC TABULATE will be a little different than the original. Since it is only printing precalculated numbers, it will use the SUM statistic all the time.

Good luck.

Hi:

When you say you are outputting the table via ODS, are you using ODS HTML, ODS RTF or ODS PDF?

TABULATE does not have a way to delete report columns (or rows). Normally, if you are calculating information with TABULATE and you don't want to show certain rows or columns, then you create an output dataset from TABULATE and delete the information you do NOT want, after the percentages are calculated. Then you pass this filtered data to another procedure (such as PROC PRINT or PROC REPORT).

The thing is that the output dataset from TABULATE does not maintain the same structure as what you see in the output report. So, you may have to do some data manipulation to "massage" the data that you get out from TABULATE into the form that you want.

For example, I mocked up some sample data -- just using Y or N for the INSTATE variable. If you look at the output from TABULATE (WORK.PCTOUT) versus ODS, you will see how the structure changes.

Thanks for such useful answers, both of you. I'm actually using ODS tagsets.excelxp to output the data. I have noticed that ODS html and pdf have a few extra ways to hide columns, etc., so I might consider doing that. Outputting a dataset and filtering the data might work for me too, so I'll look into doing that.

Hi! Could you guide on how to use PROC HTML to hide my columns? Thanks in advance! 🙂

Hi:
HTML is not a "PROC". HTML is a destination. You use ODS HTML To create output from SAS procedures like PROC REPORT and PROC TABULATE. ODS HTML does not really provide a way to hide columns. ODS EXCEL and ODS TAGSETS.EXCELXP do provide ways to hide columns, but it's not always easy to figure the columns that you want to hide and I've never tried to use columns that might have spanning headers above them.

The usual way to hide columns, no matter what procedure you're using in the scenario where you want to use ALL the values for the overall count, but you want to not show some columns or subgroups for some reason is to make 2 passes through the data. One pass to summarize and get the numbers and statistics using ALL the values. Then you create an output dataset from the first pass and use the summarized dataset to pass to your report procedure. Usually in between the first pass and the final report pass, you eliminate the rows or columns you don't want with a DATA step program or some other kind of subsetting procedure.
