recompose: Recompose a data frame into another form

In 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")

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.

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"))
