"""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."""
