cover: Cover page

In surveyeditor: Generate a Survey that can be Completed by Survey Respondents

Description

Front and back cover page of the survey.

Usage

cover(type = c("front", "back"), content, col, size, loc, time = NULL)

Arguments

type	To indicate if the cover is a front of a back cover page. If back page, time must be set. See Details for other differences.
content	Texts to be displayed in the slide. It can be a vector c( ) containing multiple items.
col	The colour of content hence its length must be the same as that of content.
size	The font size of content hence its length must be the same as that of content.
loc	The vertical location of content. Must be a number within the interval [0,100]. Its length must be the same as that of content.
time	The time (in seconds) that the slide is displayed for. Works only type="back". See Details.

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,...)
}

Value

A slide is displayed on the graphic device and no output in the console.
