R: Remove observations with missing values

na.rm {questionr} | R Documentation

## Remove observations with missing values

### Description

`na.rm` is similar to na.omit but allows to specify a list of variables to take into account.

### Usage

    na.rm(x, v = NULL)

### Arguments

`x` | a data frame
`v` | a list of variables

### Details

If `v` is not specified, the result of `na.rm` will be the same as na.omit. If a list of variables is specified through `v`, only observations with a missing value (`NA`) for one of the specified variables will be removed from `x`. See examples.
