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.

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"))
