Details

strview2qualtrics

For strview2rate(), the lengths of questions and choices must match. For example, when questions = c('1. To what existence you can feel pleasant if you were in this environment', '2. To what existence you can feel safe if you were in this environment'), choices could be list(c('Unpleasant', 'Less pleasant', 'More pleasant', 'Pleasant'), c('Unsafe', 'Less safe', 'Safer', 'Safe')) For strview2pwc, the choices are always c('left', 'right') for the coparison purposes.

Examples

data('scdataframe')
header <- "Please review the following picture(s):"
questions <- c('1. To what extent you feel pleasant if you were in this environment',
              '2. To what extent you feel safe if you were in this environment')
choices <- list(c('Unpleasant','Less pleasant', 'Pleasant', 'More pleasant'),
                c('Unsafe', 'Less safe','Safe', 'Safer'))
txt <- streetscape::strview2rate(scdataframe, header, questions, choices)

data('scdataframe')
header <- "Please review the following picture(s):"
questions <- 'which one is more beautiful?'
txt <- streetscape::strview2pwc(scdataframe, k=1, header, questions)
