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