I have adherence level for 6 different drugs (drug1, drug2, etc..),
inside cohort datafile, followed over 12 months.
At every visit there are data for 3 out of 6 drugs and I want to have
new variable having the minimal value for drug adherence, example
below

id  visit  drug1  drug2  drug3  drug4  drug5  drug6  minval
1       2     10     20     30      .      .      .      10
2       2     40     30      .     50      .      .      30
etc..

egen minval = rowmin(drug1-drug6)
