plot.data_descr: Plot descriptive statistics for partial rankings

Description

plot method for class "data_descr".

Usage

# S3 method for data_descr
plot(
  x,
  cex_text_mean = 1,
  cex_symb_mean = 12,
  marg_by = "item",
  cex_text_pc = 3,
  cex_range_pc = c(8, 20),
  ...
)

Value

Produce 5 plots to display descriptive summaries of the partial ranking dataset, namely: i) a barplot of the frequency distribution (%) of the number of items actually ranked in each partial sequence, ii) a basic pictogram of the mean rank vector, iii) a heatmap of the marginal distirbutions (either by item or by rank), iv) the ecdf of the marginal rank distributions and v) a bubble plot of the pairwise comparison matrix.

Arguments

x

An object of class "data_descr" returned by data_description.

cex_text_mean

Positive scalar: the magnification to be used for all the labels in the plot for the mean rank vector. Defaults to 1.

cex_symb_mean

Positive scalar: the magnification to be used for the symbols in the pictogram of the mean rank vector. Defaults to 12.

marg_by

Character indicating whether the marginal distributions must be reported by "item" or by "rank" in the heatmap. Defaults to "item".

cex_text_pc

Positive scalar: the magnification to be used for all the labels in the bubble plot of the paired comparison frequencies. Defaults to 3.

cex_range_pc

Numeric vector indicating the range of values to be used on each axis in the bubble plot of the paired comparison frequencies. Defaults to c(8,20).

...

Further arguments passed to or from other methods (not used).

Examples

## Example 1. Plot sample statistics for the Antifragility dataset.
r_antifrag <- ranks_antifragility[, 1:7]
desc <- data_description(r_antifrag)
plot(desc)

## Example 2. Plot sample statistics for the Sports dataset.
r_sports <- ranks_sports[, 1:8]
desc <- data_description(rankings = r_sports, borda_ord = TRUE)
plot(desc, cex_text_mean = 1.2)

## Example 3. Plot sample statistics for the Sports dataset by gender.
r_sports <- ranks_sports[, 1:8]
desc_f <- data_description(rankings = r_sports, subset = (ranks_sports$Gender == "Female"))
plot(desc_f, cex_text_mean = 1.2)
desc_m <- data_description(rankings = r_sports, subset = (ranks_sports$Gender == "Male"))
plot(desc_m, cex_text_mean = 1.2)
