Lets say I have the following data of sock increase per drawer
>socks
year drawer_nbr sock_total
1990 1 2
1991 1 2
1990 2 3
1991 2 4
1990 3 2
1991 3 1
I would like to have a binary variable that identifies if the socks have increased in each drawer. 1 if they increased and 0 if not. The result would be
>socks
drawer_nbr growth
<dbl> <factor>
1 0
2 1
3 0
I am getting stuck on comparing sock_total of one year vs sock_total of another year. I know that I need to use dplyr::summaries(), but I am having difficulty with what goes inside that function.
