  • matA (matrix)

  • matU (matrix)

  • matF (matrix)

  • matC (matrix)

  • MatrixClassAuthor (character vector)

  • MatrixClassOrganized (character vector)

  • MatrixClassNumber (integer vector)

cdb_unnest(cdb, components = c("matA", "matU", "matF", "matC",
  "MatrixClassAuthor", "MatrixClassOrganized", "MatrixClassNumber"))

Arguments

cdb

A CompadreDB object
components

Character vector specifying which components to extract.

Defaults to all, i.e. c("matA", "matU", "matF", "matC", "MatrixClassAuthor", "MatrixClassOrganized", "MatrixClassNumber")

Value

cdb with additional list-columns for each element of argument components

Examples

# unnest all components
CompadreUnnest <- cdb_unnest(Compadre)

# unnest select components (matU and MatrixClassAuthor)
CompadreUnnest <- cdb_unnest(Compadre, c("matU", "MatrixClassAuthor"))
