## Arguments

x |
An object from which to extract element(s) or in which to replace
element(s). |

i, j |
Indices specifying elements to extract or replace. Indices are
`numeric` , `integer` or `character`
vectors or empty (missing) or `NULL` . Numeric values are coerced to
`integer` as by `as.integer` (and hence truncated
towards zero). Character vectors will be matched to the name of the
elements. An empty index (a comma separated blank) indicates that all
entries in that dimension are selected. |

drop |
A `logical` scalar: should the result be coerced to
the lowest possible dimension? This only works for extracting elements,
not for the replacement. |

## Value

A subsetted object.
