Preview every participant's sort — plot

Draws each participant's completed sort as their own pyramid: one tile per statement, stacked in its grid column, colored along the disagree-agree axis. This is the look-at-the-decisions-first view: run it straight after import, before any analysis, to see how every participant grouped the statements. plot(qdata) does the same.

Usage

plot_sorts(x, participants = NULL, per_page = 12, labels = NULL, cex = NULL)

Arguments

x: A qsort_data object or a J x N matrix of sorts.
participants: Which participants to draw (names or indices); NULL (default) draws everyone.
per_page: How many pyramids per page (default up to 12, arranged automatically); further participants continue on the next page.
labels: Optional statement labels for the tiles (defaults to the statement ids).
cex: Tile label size; NULL (default) adapts to the tallest column.

Value

The input, invisibly.

Examples

distr <- c(1, 2, 3, 2, 1)
set.seed(1)
Y <- replicate(4, {
  r <- integer(9)
  r[order(rnorm(9))] <- rep(seq_along(distr), distr)
  r - 3                                  # printed labels -2..+2
})
plot_sorts(qsort_data(Y, distribution = distr, validate = FALSE))
