Details

If it is a front cover page (i.e. type="front") a green button is shown in the bottom of the slide to allow proceeding to the next slide. The reason that time only works for type="back" is that the back cover page closes in a few seconds so the entire survey program starts again for the next subject if the command repeat{} is used. For example, repeat{cover(type="front",...) identity(...) slide(...) slide(...) ... read.write(...) cover(type="back",time=10,...) }
