This function writes a report_spec object to the file system, using the specifications provided in the object.

write_report(x, file_path = NULL, output_type = NULL, preview = NULL)

Arguments

x

The report object to write.

file_path

The file name and path to write the report to. If supplied, this parameter overrides the file_path parameter on the create_report function. Default is NULL.

output_type

The output file type. This parameter will override the output_type on the create_report function. This parameter can be used to output the same report object to multiple output types. Default value is NULL, meaning it will not override the create_report value. Valid values are 'TXT', 'RTF', and 'PDF'.

preview

Whether to write the entire report, or a report preview. A report preview is a subset of pages of the report. The default value is NULL, meaning the entire report will be written. You may also pass a number of pages to write. For example, passing the number 1 will print the first page, while passing a 5 will print the first five pages.

Value

The report spec, with settings modified during rendering. These modified settings can sometimes be useful for documentation, and for debugging issues with the procedure.

Details

The function renders the report in the requested format, and writes it to the location specified in the report file_path parameter. Attempts to write an object that is not of class "report_spec" will generate an error.

The write_report function is a driver for very complex set of rendering functions. The rendering functions perform most of the advanced functionality of the reporter package: generating spanning headers, page wrapping and breaking, creating stub columns, etc. When things go wrong, they will usually go wrong during this function call. For that reason, although this function can be part of the pipeline that creates the report object, it is best to call write_report independently, to help isolate any issues from the report definition procedure.
