matrix_tidiers: 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)
