Plotting Paired Comparison Data
Plotting the frequency table from "paircomp" data.
## S3 method for class 'paircomp' plot(x, off = 0.05, xlab = "Proportion of comparisons", ylab = "", tol.xlab = 0.05, abbreviate = TRUE, hue = NULL, chroma = 40, luminance = 80, xlim = c(0, 1), ylim = NULL, xaxs = "i", yaxs = "i", ...)
x |
an object of class |
off |
numeric. Offset between segments on the y-axis. |
xlab, ylab |
character. Axis labels. |
tol.xlab |
numeric. convenience tolerance parameter for x-axis annotation. If the distance between two labels drops under this threshold, they are plotted equidistantly. |
abbreviate |
logical or integer. Should object labels be abbreviated? Alternative an integer with the desired abbreviation length. The default is some heuristic based on the length of the labels. |
hue |
numeric. A vector of hues in [0, 360], recycled to the
number of objects compared in |
chroma |
numeric. Maximum chroma in the palette. |
luminance |
numeric. Minimum (and maximum) luminance in the palette. If omitted, the maximum is set to 95. |

The plot method creates a frequency table (using summary)
and visualizes this using a sort of spine plot with HCL-based
diverging palettes. See Zeileis, Hornik, Murrell (2009) for the
underlying ideas.
