recompose: Recompose a data frame into another form

In tidymodels/hardhat: Construct Modeling Packages

Recompose a data frame into another form

Description

recompose() takes a data frame and converts it into one of:

• A tibble

• A data frame

• A matrix

• A sparse matrix (using the Matrix package)

This is an internal function used only by hardhat and recipes.

Usage

recompose(data, ..., composition = "tibble", call = caller_env())

Arguments

data	A data frame.
...	These dots are for future extensions and must be empty.
composition	One of: "tibble" to convert to a tibble. "data.frame" to convert to a base data frame. "matrix" to convert to a matrix. All columns must be numeric. "dgCMatrix" to convert to a sparse matrix. All columns must be numeric, and the Matrix package must be installed.
call	The call used for errors and warnings.

Value

The output type is determined from the composition.

Examples

df <- vctrs::data_frame(x = 1)

recompose(df)
recompose(df, composition = "matrix")

# All columns must be numeric to convert to a matrix
df <- vctrs::data_frame(x = 1, y = "a")
try(recompose(df, composition = "matrix"))
