AddDummyVariablesForNAs

R Documentation

Add dummy variables to a `data.frame` suitable for regression models.

Description

Appends a matrix to a data.frame containing columns of dummy variables. It assumes the input data is suitable for regression and contains a single column for an outcome variable. Other columns would be for individual predictors used in the regression. The appended columns of dummy variables indicate the missing status of each predictor. i.e. 1 if the predictor is missing in that case, zero otherwise. A column is added for each predictor that has at least one case of missing data.

Usage

AddDummyVariablesForNAs(data, outcome.name, checks = TRUE)

Arguments

`data`	A `data.frame` of the data to be used for a Regression model assuming a single outcome.
`outcome.name`	A `characater` of the name of the outcome variable in the data.
`checks`	A `logical` to determine if further checks are done to remove cases from the data. If `TRUE`, cases are removed if all predictors are missing or if the response is missing.
