what is default for add_line argument for the plot_profiles() function?

[jrosen48]

Here is the documentation:

plot_profiles(
  x,
  variables = NULL,
  ci = 0.95,
  sd = TRUE,
  add_line = TRUE,
  rawdata = TRUE,
  bw = FALSE,
  alpha_range = c(0, 0.1),
  ...
)

## Default S3 method:
plot_profiles(
  x,
  variables = NULL,
  ci = 0.95,
  sd = TRUE,
  add_line = FALSE,
  rawdata = TRUE,
  bw = FALSE,
  alpha_range = c(0, 0.1),
  ...
)

Documentation for add_line:

Logical. Whether to display a line, connecting cluster centroids belonging to the same latent class. Defaults to TRUE. Note that the additional information conveyed by such a line is limited.

But, the default tidyLPA class method has add_line = FALSE.
