I'm trying to work with sales in a real time, and I want to predict it.
However when I read the file my date variable is detected as a character, and I just use the function dmy_hms to get in the proper format.
When I try to transform my df as a tsibble object I got duplicates, I did find some article to try to fix this problem : Electricity demand data in tsibble format | Rob J Hyndman , but i got the following the error:
Error: Problem with
..1 must be of size 1, not size 24733.
The error occurred in group 1: CUPOM = 46462.
I really do not know how to create a minimal reproduce example to elucidate my question,
If someome could help me would be appreciated.
