na.rm: Remove observations with missing values

na.rmR 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.
