Export to a Word document

Source: R/export_as_docx.R
export_as_docx.Rd

From an rtables table, produce a self-contained Word document or attach it to a template Word file (template_file). This function is based on the tt_to_flextable() transformer and the officer package.

Usage 

export_as_docx(
  tt,
  file,
  add_page_break = FALSE,
  titles_as_header = TRUE,
  integrate_footers = TRUE,
  section_properties = section_properties_default(),
  doc_metadata = NULL,
  template_file = NULL,
  ...
)

section_properties_default(
  page_size = c("letter", "A4"),
  orientation = c("portrait", "landscape")
)

margins_potrait()

margins_landscape()

Arguments

tt

(TableTree or related class)
a TableTree object representing a populated table.

file

(string)
output file. Must have .docx extension.

add_page_break

(flag)
whether to add a page break after the table (TRUE) or not (FALSE).

titles_as_header

(flag)
Controls how titles are rendered relative to the table. If TRUE (default), the main title (formatters::main_title()) and subtitles (formatters::subtitles()) are added as distinct header rows within the flextable object itself. If FALSE, titles are rendered as a separate paragraph of text placed immediately before the table.

integrate_footers

(flag)
Controls how footers are rendered relative to the table. If TRUE (default), footers (e.g., formatters::main_footer(), formatters::prov_footer()) are integrated directly into the flextable object, typically appearing as footnotes below the table body with a smaller font. If FALSE, footers are rendered as a separate paragraph of text placed immediately after the table.

section_properties

(officer::prop_section)
an officer::prop_section() object which sets margins and page size. Defaults to section_properties_default().

doc_metadata

(list of string)
any value that can be used as metadata by officer::set_doc_properties(). Important text values are title, subject, creator, and description, while created is a date object.

template_file

(string)
template file that officer will use as a starting point for the final document. Document attaches the table and uses the defaults defined in the template file.

...

(any)
additional arguments passed to tt_to_flextable().

page_size

(string) page size. Can be "letter" or "A4". Defaults to "letter".

orientation

(string) page orientation. Can be "portrait" or "landscape". Defaults to "portrait".

Value

No return value, called for side effects

Details

Pagination Behavior for Titles and Footers (this behavior is experimental at the moment):

The rendering of titles and footers interacts with table pagination as follows:

  • Titles: When titles_as_header = TRUE (default), the integrated title header rows typically repeat at the top of each new page if the table spans multiple pages. Setting titles_as_header = FALSE renders titles as a separate paragraph only once before the table begins.

  • Footers: Regardless of the integrate_footers setting, footers appear only once. Integrated footnotes (integrate_footers = TRUE) appear at the very end of the complete table, and separate text paragraphs (integrate_footers = FALSE) appear after the complete table. Footers do not repeat on each page.

Functions

  • section_properties_default(): Helper function that defines standard portrait properties for tables.

  • margins_potrait(): Helper function that defines standard portrait margins for tables.

  • margins_landscape(): Helper function that defines standard landscape margins for tables.

Note

export_as_docx() has few customization options available. If you require specific formats and details, we suggest that you use tt_to_flextable() prior to export_as_docx(). If the table is modified first using tt_to_flextable(), the titles_as_header and integrate_footers parameters must be re-specified.

Examples 

lyt <- basic_table() %>%
  split_cols_by("ARM") %>%
  analyze(c("AGE", "BMRKR2", "COUNTRY"))

tbl <- build_table(lyt, ex_adsl)

# See how the section_properties_portrait() function is built for customization
tf <- tempfile(fileext = ".docx")
export_as_docx(tbl,
  file = tf,
  section_properties = section_properties_default(orientation = "landscape")
)
