Methods for the FBM class

Accessor methods for class `FBM`

. You can use positive and negative indices,
logical indices (that are recycled) and also a matrix of indices (but only
positive ones).

- x
A FBM object.

- i
A vector of indices (or nothing). You can use positive and negative indices, logical indices (that are recycled) and also a matrix of indices (but only positive ones).

- j
A vector of indices (or nothing). You can use positive and negative indices, logical indices (that are recycled).

- ...
Not used. Just to make nargs work.

- drop
Whether to delete the dimensions of a matrix which have one dimension equals to 1.

- value
The values to replace. Should be of length 1 or of the same length of the subset to replace.
