Convert an idaifield_simple-list to a Matrix

Source: R/idaifield_as_matrix.R
idaifield_as_matrix.Rd

Converts a list of class idaifield_docs, idaifield_resource or idaifield_simple into a matrix. Recommended to use with idaifield_simple-lists as returned by simplify_idaifield(). If given a list of class idaifield_docs containing all meta-info, it will automatically unnest to resource level. It is recommended to select the list first using idf_select_by() from this package to reduce the amount of columns returned. See example.

Usage

idaifield_as_matrix(idaifield)

Arguments

idaifield

An object as returned by get_idaifield_docs(), check_and_unnest() or simplify_idaifield()

Value

a matrix (depending on selection and project database it can be very large)
