Make Bertin display of grid data.
Description
One of the most popular ways of displaying grid data has been adopted from Bertin's (1974) graphical proposals, which have had an immense influence onto data visualization. One of the most appealing ideas presented by Bertin is the concept of the reorderable matrix. It is comprised of graphical displays for each cell, allowing to identify structures by eye-balling reordered versions of the data matrix (see Bertin, 1974). In the context of repertory grids, the display is made up of a simple colored rectangle where the color denotes the corresponding score. Bright values correspond to low, dark to high scores. For an example of how to analyze a Bertin display see e.g. Dick (2000) and Raeithel (1998).
Usage
bertin(
x,
colors = c("white", "black"),
showvalues = TRUE,
xlim = c(0.2, 0.8),
ylim = c(0, 0.6),
margins = c(0, 1, 1),
cex.elements = 0.7,
cex.constructs = 0.7,
cex.text = 0.6,
col.text = NA,
border = "white",
lheight = 0.75,
id = c(T, T),
cc = 0,
cr = 0,
cc.old = 0,
cr.old = 0,
col.mark.fill = "#FCF5A4",
print = TRUE,
...
)
