Hello,
I recently created many variables (s1,s2,s3,...,s20).
I can run group_by(s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15,s16,s17,s18,s19,s20)
But I don't know how to simplify that only declaring the first and last variable.
Something like group_by(s1:s20)
Is it possible to do that?
Thanks for your time and interest.
