Hello.
I have a dataset that has the following set up.
member_id sold_dt product
1 xx/xx/xxxx a
1 xx/xx/xxxx b
1 xx/xx/xxxx b
1 xx/xx/xxxx c
2 xx/xx/xxxx a
2 xx/xx/xxxx a
2 xx/xx/xxxx a
2 xx/xx/xxxx b
What I want to do is end up with a dataset with the following set up:
member_id product_cnt
1 3
2 2
I want a count of the unique products.
