Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

A block of code is set as follows:

  output$reacDomains <- renderUI({
    
    domainList = unique(as.character(passData()$networkDomain))
    
    selectInput("subDomains", "Choose subdomain", domainList)
    
  })

Code words in text are shown as follows: "They should be named server.R and ui.R."

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "You can see the function names (checkboxGroupInput and checkboxInput) as numbered entries on the left-hand side panel".
