complete cases is cci().
Usage
ici(x)
Arguments
x
An R object. Currently supported are
methods for the following classes: mids,
data.frame and matrix. In addition,
x can be a vector of any kind.
Value
Logical vector indicating the incomplete cases, . If
x is a data.frame or matrix the length
is nrow(x). In other cases, the length is
length(x).
