R: Tidiers for matrix objects

matrix_tidiers {broom} | R Documentation

## Tidiers for matrix objects

### Description

These perform tidying operations on matrix objects. `tidy` turns the matrix into a data.frame while bringing rownames, if they exist, in as a column called `.rownames` (since results of tidying operations never contain rownames). `glance` simply reports the number of rows and columns. Note that no augment method exists for matrices.

### Usage

    ## S3 method for class 'matrix'
    tidy(x, ...)

    ## S3 method for class 'matrix'
    glance(x, ...)

### Arguments

`x` | A matrix
`...` | extra arguments, not used

### Value

`tidy.matrix` returns the original matrix converted into a data.frame, except that it incorporates rownames (if they exist) into a column called `.rownames`.

`glance` returns a one-row data.frame with

`nrow` | number of rows
`ncol` | number of columns
`complete.obs` | number of rows that have no missing values
`na.fraction` | fraction of values across all rows and columns that are missing

### Examples

    mat <- as.matrix(mtcars)
    tidy(mat)
    glance(mat)
