Instructions.html

  <div id="instructions" class="hidden">
Instructions are separated for the sections of this interface. Take a quick look at the rest of the page to familiarise yourself with the overall layout before reading the instructions for using each section.

  <button onclick="toggleText('InstructionsGettingStarted')">
    Show/hide instructions for getting started
    </button>

  <div id="InstructionsGettingStarted" class="hidden">

The Getting Ready section makes sure the interface is ready to go, and is operating in the correct working directory. Check the current working directory and the R version; if both are correct, hit the "get working" button. <p>
If the R version is not showing, you have major problems relating to the installation of R, or this interface cannot link up with the installation. <p>
If the current directory is not where you want to be working, you will need to hit the "change directory" button.
    </div>


  <button onclick="toggleText('InstructionsOutput')">
    Show/hide instructions for the output section
    </button>

  <div id="InstructionsOutput" class="hidden">
    The output section is actually both input and output. Once commands are executed, they will be printed at the bottom of the existing output. They will appear using  heading level 4 HTML tags or graphics but will be clearly identifiable. <p>
    In order to read the most recent output using a screen reader, you will need to move forward and back using the hot keys for any standard web page. Remember you can move forwards to the next graphic using "g" and back to the previous one using "shift+g".

  <button onclick="toggleText('InstructionsNextSteps')">
    Show/hide instructions for the next steps section.
    </button>
  <div id="InstructionsNextSteps" class="hidden">
      When you are ready to type commands, go to the only edit box on this creen. You can type commands or copy and paste them into the box. To execute the commands just click on the next button called "Execute". N.B. Execution of code is only possible if you have specified the working directory in the Getting Started section.<br>
      If you have finished entering commands, look to save your work using one or more of the other three buttons at the bottom of this page. These buttons will:
      <ol>
        <li>save all the work done including input and output,</li>
        <li>save your commands as an R script, or</li>
        <li>save your commands in the form of an R markdown file.</li>
      </ol>
      When you click a button to save your work, you will be prompted to choose a filename etc.
