Extracting complete cases is also known as 'listwise
deletion' or 'complete case analyses'. cc(x) is
equivalent to na.omit(x). Missing values in x
are coded as NA. The companion function for
selecting the incomplete cases is ic().
Usage
cc(x, drop = TRUE)
Arguments
x
An R object. Currently supported are
methods for the following classes: mids,
mira, mipo, data.frame and
matrix. In addition, x can be a vector of
any kind.
drop
A logical flag for matrices and arrays. If
drop=TRUE the result is coerced to the lowest
possible dimension.
Value
A vector, matrix of data.frame
containing the data of the complete cases.
