Handle Missing Values in Objects

Description

These generic functions are useful for dealing with NAs in e.g., data frames. na.fail returns the data frame if it does not contain any missing values, and signals an error otherwise. na.omit returns the data frame with incomplete cases removed.

Usage

na.fail(object)
na.omit(object)

Arguments

na.fail(DF)#> Error: missing values in ..
