Sum of several dummy variables

[Beatriz Gomes]

Hello!
I want to create a new variable that sums all of this dummy variables

 
 Rsuppdoc Rsuppleg Rsuppjob Rsuppaprt Rsupphealth Rsuppeduc Rsuppeduc2 RsuppAT Rsuppfood Rsupppsyc

They are simple dummy variables that take the value of 1 if "yes" and 0 otherwise.

The code I wrote to achieve my goal was:

egen sumsupp = rowtotal(Rsuppdoc Rsuppleg Rsuppjob Rsuppaprt Rsupphealth Rsuppeduc Rsuppeduc2 RsuppAT Rsuppfood Rsupppsyc)

Nevertheless the new variable "sumsupp" is giving me values from 0-8 instead of being a dummy variable (1 or 0) or is it ok the way I´m doing?

tab sumsupp

    sumsupp |      Freq.     Percent        Cum.
------------+-----------------------------------
          0 |        459       56.04       56.04
          1 |        174       21.25       77.29
          2 |         81        9.89       87.18
          3 |         52        6.35       93.53
          4 |         29        3.54       97.07
          5 |         16        1.95       99.02
          6 |          6        0.73       99.76
          7 |          1        0.12       99.88
          8 |          1        0.12      100.00
------------+-----------------------------------
      Total |        819      100.00

Thank you! Have a great year!

Indeed, in principle the total of 8 dummy (indicator) variables, each (0, 1). can run from 0 to 8.

Why do you expect a result of 0 or 1? You can get a row minimum for all of the variables being 1 and a row maximum for any of the variables being 1
