The sqldf package can be used to run sql queries on R data frames. Simply specify a sql statement enclosed by quotation marks within the sqldf() function. If you want to find the total number of rows which meets a certain condition, you can make use of sql command COUNT(). Furthermore, GROUP BY() lets you to structure the data in compliance with the levels of a particular variable.
