I would recommend here y <- subset(x, select= -someColName) which is not xref'd from ?"[" (though the obscure .subset is), and is not mentioned in the relevant section of the Introduction to R either. I once foolishly offered to amend this section of the manual, but I have subsequently realised that I haven't the faintest idea how to even start doing that.

The help page for "[" is long enough, but needs to be split/have some xrefs added for things like this. -- Brian D.
