[R] dataTable manipulation in R

[Xiaofan Li]

Dear colleague,

Is it able in R to manipulate data tables as in SQL-based databases?
Is there any good method in R to locate a special subset of data rows, which
satisfy a certain expression of restrictions (e.g. dataTable$peakValue <
3.0)? Then if located, is it able for manipulations, for example, to delete
them from the dataTable?

Cheers,
Xiaofan
