Hello Group,

Is there an easy way to query a data.frame or data.table (this is
fast!) for multiple conditions?
I don't want to use a SQL kind of statement.

I am looking for something like a subset with multiple conditions.

Any tips of the like the binary search methodology used for data.table
would also help.

Thanks in advance.
