format_xtable

Format entries in an <code>xtable</code> object into character strings. (This
is essentially a <code>format</code> method for <code>xtable</code> objects.) This is
an internal function not intended to be called by package users.

Presentation-quality tables are displayed as plots on an R
graphics device.  Although there are other packages that format tables
for display, this package is unique in combining two features: (a) It is
aware of the logical structure of the table being presented, and makes
use of that for automatic layout and styling of the table.  This avoids
the need for most manual adjustments to achieve an attractive result.
(b) It displays tables using 'ggplot2' graphics.  Therefore a table can
be presented anywhere a graph could be, with no more effort.  External
software such as LaTeX or HTML or their viewers is not required.  The
package provides a full set of tools to control the style and appearance
of tables, including titles, footnotes and reference marks, horizontal
and vertical rules, and spacing of rows and columns.  Methods are included
to display matrices; data frames; tables created by R's ftable(), table(),
and xtabs() functions; and tables created by the 'tables' and 'xtable'
packages.  Methods can be added to display other table-like objects.  A
vignette is included that illustrates usage and options available in the
package.
