Examples

if( check_valid_java_version() ){
# simple TOC -----

# Create a new document
doc = docx( title = "title" )
#leave the first page blank and add a page break
doc = addPageBreak(doc)
# add a TOC (to be refresh when document is opened)
# and add a page break
doc = addTOC(doc)
doc = addPageBreak(doc)

# add titles that will be entries in the TOC
doc = addTitle( doc, "My first title", level = 1 )
doc = addTitle( doc, "My second title", level = 1 )

# Write the object in file "addTOC_example1.docx"
writeDoc( doc, "addTOC_example1.docx" )

# custom TOC -----

doc = docx( title = "title" )

#leave the first page blank and add a page break
doc = addPageBreak(doc)

doc = addTitle( doc, "Plots", level = 1 )
doc = addPlot( doc, fun = plot,
  x = rnorm( 100 ),y = rnorm (100 ),
  main = "base plot main title"
)

doc = addParagraph( doc, value="graph example 1", stylename = "rPlotLegend" )

if( requireNamespace("ggplot2", quietly = TRUE) ){

  myplot = ggplot2::qplot(Sepal.Length, Petal.Length,
    data = iris, color = Species,
    size = Petal.Width, alpha = I(0.7))
  doc = addPlot( doc = doc, fun = print,
    x = myplot #this argument MUST be named, print is expecting argument 'x'
  )
  doc = addParagraph( doc, value="graph example 2",
    stylename = "rPlotLegend" )

}

# Because we used "rPlotLegend" as legend in plot
# , addTOC will use this stylename to define
# entries in the generated TOC
doc = addTOC(doc, stylename = "rPlotLegend")

# Write the object in file "addTOC_example2.docx"
writeDoc( doc, "addTOC_example2.docx" )
}
