Chris,
But what’s the problem? You can simply not use it?
It’s not that uncommon. `base::subset()` does this.

I don't like this idea. It adds extra that it doesn't need to. Doing it with
column numbers is more straightforward, and if all you have is names you can
get numbers by doing match() or whatever and then getting the sequence with
seq(). Having a sequence of column names is odd.

So lets say one has a data.table with the following columns
first.name, last.name, height, weight, shoe.size, eye.color, hair.length,
appendage.size, ear.length
If one wanted to just include weight through hair.length one would have to go
something such as this
dt[,list(weight, shoe.size, eye.color, hair.length)]
Is there a way to do something along the lines of
dt[,list(weight...hair.length)]
If so, can you direct me to the documentation? If not can you build it? Is it
difficult? Some data.tables have many columns.
Thanking you in anticipation.
Farrel
