Plot alexithymia proportions within VVIQ groups based on a summary table

This function creates a bar plot showing the proportions of alexithymia groups within VVIQ groups for each study as well as for the combined data across all studies. The plot includes options for customizing the appearance of the bars, text labels, facets, and overall theme.

Usage

plot_alexithymia_proportions(
  df_summary,
  var_x,
  bar_alpha = 0.3,
  bar_lw = 0.1,
  prop_threshold = 0.16,
  prop_txt_size = 1.5,
  ncol = 6,
  limits = c("hyperphantasia", "typical", "hypophantasia", "aphantasia"),
  title = NULL,
  subtitle = NULL,
  x_lab = NULL,
  y_lab = "Proportion within the VVIQ group",
  marg = 8,
  base_size = 7,
  ...
)

Arguments

df_summary

A summary data frame containing counts and proportions of alexithymia groups within VVIQ groups, typically generated using the summarise_aph_and_alexi() function.

var_x

The variable to be plotted on the x-axis (e.g., vviq_group_4).

bar_alpha

Transparency level of the bars.

bar_lw

Line width of the bar borders.

prop_threshold

Threshold for displaying proportion text labels on the bars.

prop_txt_size

Size of the proportion text labels on the bars.

ncol

Number of columns for facet wrapping.

limits

Limits for the x-axis categories.

title

Title of the plot.

subtitle

Subtitle of the plot.

x_lab

Label for the x-axis.

y_lab

Label for the y-axis.

marg

Margin size around the plot.

base_size

Base font size for the plot theme.

...

Additional arguments passed to the theme_pdf() function.

Value

A ggplot2 object representing the bar plot of alexithymia proportions within VVIQ groups.

Examples

df_summary <- summarise_aph_and_alexi(all_data, vviq_group_4)
plot_alexithymia_proportions(
  df_summary, vviq_group_4, 
  base_size = 12, 
  prop_txt_size = 3
 )
