"""Manipulate R Data Frames Using SQL.
The sqldf() function is typically passed a single argument which is an SQL
select statement where the table names are ordinary R data frame names.
sqldf() transparently sets up a database, imports the data frames into that
database, performs the SQL select or other statement and returns the result
using a heuristic to determine which class to assign to each column of the
returned data frame. The sqldf() or read.csv.sql() functions can also be
used to read filtered files into R even if the original files are larger
than R itself can handle. 'RSQLite', 'RH2', 'RMySQL' and 'RPostgreSQL'
backends are supported."""
