Plot embedding — ar_plot_embedding • associatoR

Generate two dimensional plot for associatoR object.

Usage

ar_plot_embedding(
  associations,
  color_by = NULL,
  color_set = "G",
  alpha = 0.5,
  proportion_labels = 1,
  ...
)

Arguments

associations: an associatoR object containing association data as generated by ar_import with targets defined by ar_set_targets.
color_by: name of variable to generate column facets by.
color_set: a character string specifying the color set. One of c("A","B","C","D","E","F","G","H"). See scale_color_viridis_d.
alpha: a numeric value between 0 and 1 specifying the transparency of points. Default is .5.
proportion_labels: a numeric value between 0 and 1 specifying the proportion of labels shown in the plot. Values smaller than 1 omit 1-proportion_labels of labels for lower frequency targets.
...: optional arguments passed on to geom_text_repel.

Value

Returns a ggplot plot object.

Examples

ar_import(intelligence,
          participant = participant_id,
          cue = cue,
          response = response,
          participant_vars = c(gender, education),
          response_vars = c(response_position, response_level)) %>%
  ar_set_targets("cues") %>%
  ar_embed_targets() %>%
  ar_cluster_targets() %>%
  ar_project_embedding() %>%
  ar_plot_embedding(color_by = cluster,
                    proportion_labels = .5)
#> 456 targets with count < min_count were dropped from embedding.
#> Warning: ggrepel: 7 unlabeled data points (too many overlaps). Consider increasing max.overlaps
