Dear Statalisters,
I would like to know if there is a command in Stata to convert multiple
numeric variables into a single string variable (and vice-versa). For
example, suppose I have the following dataset:
var1 var2 var3
0 2 3
4 5 6
7 8 9
In this respect, I would like to create a new string variable, say, var4,
using the var1, var2 as well as var3. That is:
var1 var2 var3 var4
0 2 3 0_2_3
4 5 6 4_5_6
7 8 9 7_8_9
Finally, I would like to do the inverse process. From:
var1
0_2_3
4_5_6
7_8_9
to
var1 var2 var3 var4
0_2_3 0 2 3
4_5_6 4 5 6
7_8_9 7 8 9
Thank you for any reply.
Best regards,
Tiago
