Hi,
I think I may be of help here.
I have read the requirements but I have a few questions to ask.
1. I think we would need to be able to know how to use your package to list the available databases, metadata and time-series data?
2. You said that we are to use the built-in R functions. Getting the moving average requires an external package that need to be installed.
I have experience using R in my role as a data scientist/analyst. I am optimistic that I can help you.
If you don't mind, may I suggest more hours to be added to get this done? I think the 1-2 hours is a bit too short and may give room for a poorly done work.
Let's discuss more through chat.
Thanks
Many Regards,
Chigozie
