class RSqldf(RPackage):
"""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."""
