[datatable-help] can one name a collection of columns by specifying just the first and the last column

[Farrel Buchinsky]

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.
