  • matA (matrix)

  • matU (matrix)

  • matF (matrix)

  • matC (matrix)

  • MatrixClassAuthor (character vector)

  • MatrixClassOrganized (character vector)

  • MatrixClassNumber (integer vector)

Usage

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.
