0 votes

This is my data set:

QTR MONTHS  SALES
Q1  JAN     100
Q1  FEB     200
Q2  MAY     300
Q2  JUN     400

I want an output like this;

Row Labels  JAN FEB MAY JUN Grand Total
Q1          100 200         300
Q2                  300 400 700
Grand Total 100 200 300 400 1000

How do I write an SQL query in R to do this?
