David, maybe the next version of Stata will answer our prayers. Eric, thank you so much for your detailed suggestions. It is greatly appreciated. I will try to use your example to create my tables. And, as you suggested, if I run into any problems I will try to consult the list again. Once again, thank you.

The first examples below are simple versions of two and three way tables with -tabout-. The last example automates this process, as I described before, including adding the labels to the new combined cross-variable (called a "by" variable below). Also, as I previously mentioned, if you've got tons of tables to produce, you can include all those variables in the loop (notice that I create a table for each combination of cross-variables for every other numeric variable in the -auto.dta- … you could use this to mass-produce your tables for many variables). I often use a version of this code to produce many tables with combined cross-vars -- you'll have to adapt the code to your data[2]. > > > ******************************* > ******************************* watch for wrapping issues below: > *----make some fake data: > sysuse auto, clear > recode rep78 (.=0) > lab def r 0 "zero" 1 "one" 2 "two" 3 "three" 4 "four" 5 "five" > lab val rep78 r > fre rep78 > *--create more BY vars: > clonevar rep782 = rep78 > clonevar foreign2 = foreign > > > > > ******************************* > *----1 twoway table > //foreign > table trunk foreign, row col miss > tabout trunk foreign using "twoway.xls", c(freq) replace > > //rep78 > table trunk rep78, row col miss > tabout trunk rep78 using "twoway.xls", c(freq) append > > > **all the twoway tables in a loop: > cap rm "twoway_loop.xls"= > foreach x in rep78 foreign rep782 foreign2 { > tabout trunk `x' using "twoway_loop.xls", c(freq) append > } > > > > > ******************************* > *-----2. combine the "by" vars to create N-way tables: > > **simple example (no automation): > egen test = group(foreign rep78), missing > ta foreign rep78 > ta test > lab def tlab 1 "domestic-zero" 2 "domestic-one" 3 "domestic-two" 4 "domestic-three" 5 "domestic-four" 6 "domestic-five" 7 "For-one" 8 "For-three" 9 "For-four" 10 "For-Five", modify > lab val test tlab > fre test > table trunk test, row col miss > tabout trunk test using "threeway_test.xls", replace c(freq) > drop test > lab drop tlab > > > > > > > > /* > THIS PROCESS OF BUILDING VAR LABELS FOR THE SUPER-COLS COULD BE TEDIOUS, A SOLUTION IS TO DO THIS IN A LOOP==> > */ > > > > > **put all the combinations of supercols in this list: > cap rm "threeway_tabouts_allvars.xls" > > /* NOTICE that you put the pairs of variables you want combined to create a cross- or column variable in the local macro 'vars' below -- so you can repeat variables that you want paired with something else.
