Do you know the RSQLite package? It uses the DBI package which gives a
common interface to various DB engines.
With it, you can explicitely treat data.frames as tables, and execute SQL
querys on them.

Subject: [R] SQL like manipulations on data frames
Is there a cheat-sheet anywhere that describes how to do SQL-like

My knowledge of R is rather limited. But from my experience
it seems
as though one can think of data frames as being similar to tables

My knowledge of R is rather limited. But from my experience it seems
as though one can think of data frames as being similar to tables in
a database: there are rows, columns, and values.
