In rqti: Create Tests According to QTI 2.1 Standard

Render an Rmd/md/xml file or rqti-object as qti xml with qtijs.

Description

Generates the qti xml file via rmd2xml. The xml is copied into the qtijs folder which transforms the xml into HTML. Finally, the HTML is displayed and the user sees a preview of the exercise or test.

Usage

render_qtijs(
  input,
  preview_feedback = FALSE,
  qtijs_path = qtijs_pkg_path(),
  ...
)

Arguments

input	The path to the input Rmd/md/xml document or an AssessmentItem, AssessmentTest, AssessmentTestOpal, AssessmentSection object.
preview_feedback	A boolean value; optional. Set TRUE value to always display feedback (for example, as a modal answer). Default is FALSE.
qtijs_path	The path to the qtijs renderer (qti.js), which will be started with servr::httw and to which xml files will be copied. Default is the QTIJS folder in the R package rqti local installation via the helper qtijs_pkg_path().
...	required for passing arguments when knitting

Details

Requires a running qtijs server, which can be started with start_server().

The preview is automatically loaded into the RStudio viewer pane if run in RStudio. Alternatively you can just open the browser at the corresponding local server url which is displayed after rendering is finished. Since the function is supposed to be called via the Knit-Button in RStudio, it defaults to the RStudio viewer pane.

Customize knit function in the Rmd file using the following YAML setting after the word knit knit: rqti::render_qtijs.

Value

An URL of the corresponding local server to display the rendering result.

Examples

  file <- system.file("exercises/sc1.Rmd", package = 'rqti')
  render_qtijs(file)
