SQL like manipulations on data frames
...t * from foo where bar < 10 ; is similar to foo[foo["bar"] < 10,] I'm just wondering how many other SQL-like manipulations can be done on a data frame? As an extreme example, is it reasonable to assume there is an R equivalent to: select bar, bat, baz, baz*100 as 'pctbaz' from foo where bar like %xyz % order by bat, baz desc ; Regards, - Robert http://www.cwelug.org/downloads Help others get OpenSource software.
