This function starts an http server with the QTIJS renderer. The renderer performs the conversion of qti.xml into HTML.
Value
The URL string for QTIJS server.
Details
The server has to be started manually by the user, otherwise the Knit Button will not work. The Button starts a new session and invoking a server there does not make much sense.
Examples
if (FALSE) { # \dontrun{
# Initiated server in qtiViewer folder
start_server()
# Initiated server in a specific folder provided by the user. This folder
# contains the QTI renderer
start_server("/pathToTheQtiRenderer/")
} # }
