Basically, this is how to use noteMD to insert a text box in your shiny ui (support markdown syntax) to pdf or word report!

• Step 1: create a textarea in shiny ui: tags$textarea( "Please using any **markdown** syntax!", id = 'markdowninput', rows = 3, style = 'width:100%;'), here we know the id of this tag is markdowninput (you can name whatever you want)

• Step 2: if you want to have a preview in shiny app like the demo, use output$htmlmarkdown = reactive({note_in_html(input$markdowninput) }) , then htmlOutput('htmlmarkdown') in shiny ui

• Step 3: if your report is in pdf, put note_in_md_pdf(input$markdowninput) in an R chunk (whereever you want to insert the text); if your report is in word, put note_in_md_word(input$markdowninput) in an R chunk!

Future improvements:

• Support math formula writting

Enjoy!
