Plot Iota2

Source: R/plots.R
plot_iota.Rd

Function for creating a plot object that can be plotted via 'ggplot2'.

Usage

plot_iota(
  object,
  xlab = "Amount on all cases",
  ylab = "Categories",
  liota = "Assignment of the true category (Iota)",
  lcase2 = "Assignment to the false category",
  lcase3 = "Assignment from the false true category",
  lscale_quality = "Scale Quality",
  lscale_cat = c("insufficent", "minimum", "satisfactory", "good", "excellent"),
  number_size = 6,
  key_size = 0.5,
  text_size = 10,
  legend_position = "bottom",
  legend_direction = "vertical",
  scale = "none"
)

Arguments

object

Estimates of Iota 2 created with compute_iota2(), check_dgf() or check_new_rater().

xlab

Character passed to xlab() from scale_fill_manual(). Label of the x-axis.

ylab

Character passed to ylab() from scale_fill_manual(). Label of the y-axis.

liota

Character passed to labels() from scale_fill_manual(). Label for Iota.Amount of cases that are assigned to the correct category.

lcase2

Character passed to labels() from scale_fill_manual(). Label for the amount of cases that are assigned to a false category.

lcase3

Character passed to labels() from scale_fill_manual(). Label for the amount of cases that are assigned from a false category.

lscale_quality

character passed to scale_fill_manual() determining the title for the quality of a scale. Only used in conjunction with scale.

lscale_cat

Vector of strings with length 5. This vector contains the labels for each category of quality for the scale.

number_size

Double passed to geom_text() determining the size of the numbers within the plot.

key_size

Double passed to theme() determining the size of the legend keys.

text_size

Double passed to theme() determining the size of the text within the legend.

legend_position

string Position of the legend. Possible values are "bottom","right","left", "top" and "none".

legend_direction

string Layout of the items in the legend. Possible values are "horizontal" and "vertical".

scale

String for requesting an additional plot of reliability on the scale level. If scale="dynamic_iota_index" Dynamic Iota Index is used. If scale="static_iota_index" Static Iota Index is used. If scale="none" no additional plot is created.

Value

Function returns an object of class gg, ggplot illustrating how the data of the different categories influence each other.

Note

An example for interpreting the plot can be found in the vignette Get started or via vignette("iotarelr", package = "iotarelr").
