make.predictorMatrix

Creates a predictorMatrix argument

Description

This helper function creates a valid predictMatrix. The predictorMatrix is an argument to the mice function. It specifies the target variable or block in the rows, and the predictor variables on the columns. An entry of 0 means that the column variable is NOT used to impute the row variable or block. A nonzero value indicates that it is used.

Usage

make.predictorMatrix(data, blocks = make.blocks(data))

Arguments

`data`	A `data.frame` with the source data
`blocks`	An optional specification for blocks of variables in the rows. The default assigns each variable in its own block.

Value

A matrix

Examples

make.predictorMatrix(nhanes)
make.predictorMatrix(nhanes, blocks = make.blocks(nhanes, "collect"))
