Plot of the Coding Stream — plot_iota2

Function for creating an alluvial plot that can be plotted via ggplot2.

Usage

plot_iota2_alluvial(
  object,
  label_titel = "Coding Stream from True to Assigned Categories",
  label_prefix_true = "true",
  label_prefix_assigned = "labeled as",
  label_legend_title = "True Categories",
  label_true_category = "True Category",
  label_assigned_category = "Assigned Category",
  label_y_axis = "Relative Frequencies",
  label_categories_size = 3,
  key_size = 0.5,
  text_size = 10,
  legend_position = "right",
  legend_direction = "vertical"
)

Arguments

object: Estimates of Iota 2 created with compute_iota2(), check_new_rater() or with check_dgf(). Please note that the object created by check_dgf() cannot be passed directly. Only the elements of the corresponding list are compatible.
label_titel: Character containing the title of the plot.
label_prefix_true: Character representing the prefix for tagging the true categories. Character is applied to every category.
label_prefix_assigned: Character representing the prefix for tagging the assigned categories. Character is applied to every category.
label_legend_title: Character containing the title of the legend.
label_true_category: Character describing the stratum of true categories.
label_assigned_category: Character describing the stratum of assigned categories.
label_y_axis: Character. Label of the y-axis.
label_categories_size: double determining the size of the label for each true and assigned category within the plot.
key_size: double determining the size of the legend.
text_size: double 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".

Value

Returns an object of class gg and ggplot which can be shown with plot().

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