For rbind
and c
, objects of class ‘ilab’
to be combined. For cbind
, one 'ilab' object and vectors, scalars
or data frames to be appended to the 'ilab' object's $data element. See Details.
integer controlling the construction of labels. Passed
to rbind.data.frame
or base::cbind
.
logical, controlling recursion in lists. Included solely for
consistency with base::c
; no effect in c.ilab
.
object of class ‘ilab’.
An object of class ‘ilab’. The title for the returned object is the title for the first ilab object in the list.
For the cbind
method, the returned object will have additional columns in the
$data
element, and the title will be unchanged.
Because of the unusual method dispatch behaviour of base::cbind
and
base::rbind
, which use the data frame method if any objects in
'...'
are data frames, metRology masks the base package functions
in order to guarantee correct dispatch when data frames are included in '...'
.
No adverse effects are currently known, but please report any to the package maintainer.
Calling base::cbind
directly will provide a work-around if necessary.
The generic and default cbind and rbind functions defined by metRology use the first
object in '...'
to decide which method to apply. This differs from the behaviour
of these functions in the base package, which dispatch based on inspection of
all objects in '...'
(see rbind
in the base package for details).
Control is, however, passed to the base package functions if an ilab object is not first
in the list.
The rbind
method for class 'ilab' combines objects by applying
rbind
to the $data
elements in turn and then concatenating the
$distrib
and $distrib.pars
elements using the default c
method.
Combination of the $data
elements follows the rules of rbind.data.frame
;
in particular, names must match, but need not be in the same order and the return value
column classes will be coerced to match the first if necessary.
c.ilab
simply passes the objects to rbind.ilab
, using the default value
for deparse.level
. recursive
is ignored. An error is returned if any
objects in '...'
are not of class ‘ilab’.
The cbind
method for ‘ilab’ objects combines objects of class ‘ilab’
with atomic objects or data frames by applying base::cbind
to $data
in the
(single) supplied ilab object and the items listed in '...'
. base::cbind
will extend scalars, vectors or columns in data frames to length nrow(ilab$data)
if
their length is an integer fraction of nrow(ilab$data)
. Unlike base::cbind
,
cbind.ilab
does not permit vectors or data frames longer than nrow(ilab$data)
and will return an error in such cases. cbind.ilab will also return an error if any objects in
'...'
are not one of atomic, data frame or class ‘ilab’, if more than one
‘ilab’ object is supplied or if none are.
None, yet.
