[Bioc-sig-seq] Update only specific spaces of RangedData

[Christian Ruckert]

I am missing a method to update only specific spaces of a RangedData object.

Let 'x' be a 'RangedData' object.

The two existing methods are:

'x[i]': Subsets 'x' by indexing into its spaces, so the result is
           of the same class, with a different set of spaces.

'x[[j]] <- value': Sets value as column 'j' in 'x', where 'j' can
           be a character, numeric, or logical scalar that indexes into
           the columns. The length of 'value' should equal 'nrow(x)'.

I am looking for a mixture of both, something like:

x[i][[j]] <- value

which actually doesn't work this way.

Any help would be appreciated,
Christian
