R-SQL

Export to Database

Dr. Undómiel has decided to focus on the change in size of a few target rodent species over the course of the experiment(1977-2002). She has chosen , Dipodymys spectabilis, Onychomys torridus, Perymiscus erimicus, Chaetodipus penicillatus.

Write a script that uses R and SQL to:

1. Connect to the portal_mammals.sqlite.
2. Generate a data frame with year, species_id, and the average weight per year (avg_weight) for each target species.
3. Use dbWriteTable() to include your new data frame in the portal_mammals.sqlite. Call it something informative so that Dr. Undómiel can find it easily.
