Functions cbind() and rbind() are defined in
the mice package in order to
enable dispatch to cbind.mids() and rbind.mids()
when one of the arguments is a data.frame.
cbind(...)rbind(...)
(generalized) vectors or matrices. These can be given as named
arguments. Other R objects may be coerced as appropriate, or S4
methods may be used: see sections ‘Details’ and
‘Value’. (For the "data.frame" method of cbind
these can be further arguments to data.frame such as
stringsAsFactors.)
The standard base::cbind() and base::rbind()
always dispatch to
base::cbind.data.frame() or base::rbind.data.frame()
if one of the arguments is a
data.frame. The versions defined in the mice
package intercept the user command
and test whether the first argument has class "mids". If so,
function calls cbind.mids(), respectively rbind.mids(). In
all other cases, the call is forwarded to standard functions in the
base package.
