tblentries ObjectPromote a data frame to a tblEntries object. This is an internal
function not intended to be called by package users.
as.tblEntries(x)An object of S3 class tblEntries and data.frame.
An object inheriting from data.frame. Each row represents one
table entry, with information about its content, location, and structural
role in the table. See dfSpecs for the required columns and types,
and tblEntries for a description of these columns. x must
also have attributes rowhier and colhier with information
about the row and column header hierarchies (see headerRuns).
Normally table entries are created from a textTable object via
function tblEntries. This function allows them to be created or
edited directly in a data frame.
Columns arow1, arow2, acol1 and acol2 refer to
row and column numbers in the augmented row-column grid of the table; see
adim for more information.
If x is already a tblEntries object, this function does some
validity checks. If x is NULL, a valid but empty tblEntries
object is returned.
