Use bookmarks to replace content

docx objects can generate Word documents using bookmarks as placeholders to insert contents.

Use the function docx with argument template to create a document based on an Word document where bookmarks are located.

Functions addFlexTable, addPlot, addParagraph and addImage can send respective outputs into these bookmarks. All of them have an optional argument named bookmark corresponding the the bookmarked content to replace.

Content (plots, paragraphs or images) will replace the whole paragraph containing the bookmark.

When used with addFlexTable, content (table) will be added after the paragraph containing the bookmark.

In a Word document, paragraphs and tables are different containers; a Word table contains paragraphs but is not a paragraph object. Because Word bookmarks are located in paragraphs, it is not possible to bookmark a table.


We will use a specific file as template bookmark_example.docx containing various styles and bookmarks located in the package.

library( ReporteRs )
target_file <- "bookmark_example.docx" # file to produce
template <- system.file(package = "ReporteRs",
"templates/bookmark_example.docx" ) # template example
doc = docx( template = template )
##            Normal         heading 1         heading 2            header 
##          "Normal"          "Titre1"          "Titre2"          "En-tte" 
##            footer             Title             rcode   figurereference 
##      "Pieddepage"           "Titre"           "rcode" "figurereference" 
##    tablereference             small 
##  "tablereference"           "small"


Let use iris to illustrate tables and graphics.

library( ggplot2 )
ft <- vanilla.table( data = head(iris), add.rownames=TRUE )
myplot1 <- ggplot(data = iris, aes(Sepal.Length, Petal.Length, color = Species),
alpha = I(0.7) )

Use list_bookmarks to check available bookmarks in the template document:

## [1] "PLOT"     "DATA"     "AUTHOR"   "REVIEWER"

Finally, add all elements into the report and write it into file target_file.

library( magrittr )
doc %>%
addParagraph( value = "Jane Doe", stylename = "small", bookmark = "AUTHOR" ) %>%
addParagraph( value = "John Doe", stylename = "small", bookmark = "REVIEWER" ) %>%
addFlexTable( flextable = ft, bookmark = "DATA" ) %>%
addPlot( fun = print, x = myplot1, bookmark = "PLOT" ) %>%
writeDoc( file = target_file)

Declare bookmark in Word

To be used with a docx object, bookmark must be placed into a single paragraph, you have to add the bookmark on a portion of a text in a paragraph.

If placed along 1 or more paragraphs, produced document will be corrupted.

To add a bookmark that ReporteRs will use later, do not add the bookmark on the whole paragraph** but rather in the paragraph.

This operation is to be done in Word, by editing the template of the document.

Below an example that will not work (bookmark brackets are on the whole paragraph):

Nested table and table headers

Word is not able to repeat header cells if table is nested in another table.

In a Word document, if a table contains a bookmark used to add another table (therefore creating a nested table), table headers won’t be repeated along pages.
