R developer to write sample code

I need an R developer to make a small example for a student on how to use data from an R package.

I need example code ( with comments) that a beginner student can use with my R package to list the available databases , get metadata and time series data. The report uses R commands that are built into the package to get this data.

I need the results from the 3 commands to be converted to dataframes.

Then
a). display the all fields in the dataframe (and their data types in a hierarchical order)
b). Example code showing how to access elements in the dataframe.
c). List the first 5 and last 5 results.

One of the commands returns a timeseries.
Display the first 30 results with a 7 day moving average of all columns in the time series.

The point of the project is a provide a simple "R" demonstration. that any student can use
You'll need to install the R package to get the data.

I need this in RStudio ASAP. It's 1-2 hours work.
If you think it takes 7 days then please don't bid.

Don't bid to then try negotiate a price . Bid what you want to charge - $50 max
