A new report_spec object.
This function is the constructor for the report object. The report object contains information needed to create a report. The object is defined as an S3 object, and has a class of 'report_spec'.
The report object holds information concerning report page size, orientation,
titles, footnotes, page header, page footer, margins, and other options.
Use the add_content function to add content to the report.
The report may be written to a file using the write_report
function.
The report is the primary container for report specifications. The
following functions add additional specifications to the report object
initialized with create_report.
titles to add titles to the report.
footnotes to add footnotes to the report.
title_header to add a title header to the report.
page_header to add a page header to the report.
page_footer to add a page_footer to the report.
add_content to add content to the report.
options_fixed to set options for fixed-width output.
add_content to add content to the report.
write_report to write the report to the file system.
The report family of functions are pipe-friendly. After creating the report, you may pipe the object to any of the above functions to append additional options.
Note that PDF output has some limitations not found in TXT and RTF output. See NotesOnPDF for additional information.
create_table, create_text, and
create_plot functions
to create content for the report.
