Description

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

Arguments

x

drop

A logical flag for matrices and arrays. If drop=TRUE the result is coerced to the lowest possible dimension.
