These methods alter the audited object and return it with an updated
transaction table. They generate drop
transactions.

The most important arguments here are id
and od
. All the others
are passed through to related functions.
id
and od
will always have informative defaults. However, you will often
want to supply customized values. id
is a label for the set of rows that is returned.
od
is a label for the set of rows that is dropped; it will be used for plotting.
When supplying id
or od
, remember to maintain the proper number of dimensions.
For example,
Theoph[ Theoph$WT > 70, , id = 'heavier', od = 'lighter' ]
not
Theoph[ Theoph$WT > 70, id = 'heavier', od = 'lighter' ]
The subset operator, called by all the other functions listed above, deserves
special consideration. Argument i
controls the rows that are returned.
For a data.frame
, i
may be negative, positive, zero, logical, character,
and NA, with varying effects. In particular, use of repeated
positive creates duplicates of rows, while use of NA, numeric greater than
nrow(x)
, or character not in row.names(x)
creates NA rows. [.audited
rejects indices that create NA rows. It allows duplication of rows, but it is an
error to both add and drop rows simultaneously.
For example, x[c(2,2),]
should fail, because record 1 (probably others)
is being dropped while a copy of record 2 is being added.
