Plot a bipartite respondent-modality graph

Visualises a catbipartite object with respondents on one side and modalities on the other. Respondent nodes are plotted small and unlabelled; modality nodes are plotted large and coloured by originating variable.

Usage

# S3 method for class 'catbipartite'
plot(
  x,
  show_respondents = TRUE,
  max_respondents = 500L,
  vertex_size_mod = 18,
  vertex_size_row = 2,
  ...
)

Arguments

x

A catbipartite object.

show_respondents

Logical. If TRUE (default), respondent-side vertices are drawn as small dots. If FALSE, only the modality partition is plotted (useful when the number of respondents would make the plot unreadable).

max_respondents

Integer or NULL. If the number of respondents exceeds this value and show_respondents = TRUE, a random sample of max_respondents is drawn. Set to NULL to disable. Default 500.

vertex_size_mod

Numeric. Vertex size for modality nodes. Default 18.

vertex_size_row

Numeric. Vertex size for respondent nodes. Default 2.

...

Further arguments passed to plot.igraph().

Value

Invisibly returns the input object.

Examples

df <- expand_table(Titanic)
bg <- bipartite_modality_graph(df)
plot(bg)

plot(bg, show_respondents = FALSE)
