Examples

# Plot without adjustments
study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_data_points_beeswarm() %>%
  add_mean_bar(alpha = 0.4) %>%
  add_sem_errorbar()


# New title
study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_data_points_beeswarm() %>%
  add_mean_bar(alpha = 0.4) %>%
  add_sem_errorbar() %>%
  adjust_legend(title = "My new legend title")


# New title with plotmath expression
study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_data_points_beeswarm() %>%
  add_mean_bar(alpha = 0.4) %>%
  add_sem_errorbar() %>%
  adjust_legend(title = "$E==m*c^{2}$")


# Alternative legend positions
study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_data_points_beeswarm() %>%
  add_mean_bar(alpha = 0.4) %>%
  add_sem_errorbar() %>%
  adjust_legend(position = "left")


study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_data_points_beeswarm() %>%
  add_mean_bar(alpha = 0.4) %>%
  add_sem_errorbar() %>%
  adjust_legend(position = "top")


study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_data_points_beeswarm() %>%
  add_mean_bar(alpha = 0.4) %>%
  add_sem_errorbar() %>%
  adjust_legend(position = "bottom")


# `position = "none"` hides the legend
study %>%
  tidyplot(x = treatment, y = score, color = treatment) %>%
  add_data_points_beeswarm() %>%
  add_mean_bar(alpha = 0.4) %>%
  add_sem_errorbar() %>%
  adjust_legend(position = "none")
