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.
