(description
|
||||
"The @code{sqldf} function is typically passed a single argument which is
|
||||
an SQL select statement where the table names are ordinary R data frame names.
|
||||
@code{sqldf} transparently sets up a database, imports the data frames into
|
||||
that database, performs the SQL statement and returns the result using a
|
||||
heuristic to determine which class to assign to each column of the returned
|
||||
data frame. The @code{sqldf} or @code{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.")
