Plot a csmooth_em object — plot.csmooth

Visualization for a csmooth_em object.

plot_type="scatterplot": calls plot_EM_embedding() (same behavior as smooth_em).
plot_type="elbo": plots ELBO and penalized observed-data objective traces.
plot_type="mu": plots only the component means (with arrows for 2D).

# S3 method for class 'csmooth_em'
plot(
  x,
  data = NULL,
  plot_type = c("scatterplot", "elbo", "mu"),
  dims = c(1, 2),
  two_panel = FALSE,
  verbose = FALSE,
  ...
)

Arguments

x: A csmooth_em object.
data: Numeric matrix (n x d). Required when plot_type="scatterplot" unless stored in x$data.
plot_type: One of "scatterplot", "elbo", "mu".
dims: Integer vector of length 1 or 2. Used for "scatterplot" and "mu".
two_panel: Logical; if TRUE and plot_type="elbo", draw ELBO and objective in two panels.
verbose: Logical; not passed to graphics (prevents "not a graphical parameter" warnings).
...: Passed to the underlying plotting functions.

Value

Invisibly returns x.
