Coerce a surveyframe object to a data frame

Source: R/as_data_frame.R
sframe_as_data_frame.Rd

Every surveyframe class returns its primary table. For an instrument that is the item table, for a validation result the problems, for a report the table it is mainly about. Where an object holds more than one table, the others are reachable through the named accessors in sf_accessors or, for a full tabular record of an instrument, through codebook_report().
