Hello,
I have a data frame of 56879 observations. After I run the regression, I get 48946 observations. I have tried different things, like merge them and use NAs for the missing values, then changing them to 0 after, but I keep getting :
"Error:
! Assigned data value
must be compatible with existing data.
Existing data has 56879 rows.
Assigned data has 48946 rows.
Only vectors of size 1 are recycled."
Any suggestions on how to deal with this?
