R developer for small job -- 2

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 the metadata in each database and return some time series data. The report uses one line 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 fields in the dataframe (and their data types)
b). Show 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.

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

I need this in RStudio ASAP.
