R: Creates a 'predictorMatrix' argument

make.predictorMatrix {mice} | R Documentation

## 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

### See Also

`make.blocks`

### Examples

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