Visualize estimated correlation matrix as a network

Based on approximation via simulation specified by given simulation design. Convenience wrapper for combining estimate_final_correlation and plot_cor_network.

Usage

plot_estimated_cor_network(
  obj,
  n_obs = 1e+05,
  cor_type = "pearson",
  seed = NULL,
  show_categorical = TRUE,
  return_network = FALSE,
  ...
)

Arguments

obj

S3 class object of type simdesign (or inheriting from it).

n_obs

Number of observations to simulate.

cor_type

Can be either a character (pearson, spearman, kendall) which is passed to stats::cor or a function, which is directly used to compute the correlation matrix on the simulated data. Such a function is expected to take a single input matrix (and possibly other arguments which can be set via ...) and output a single matrix.

seed

Random number seed. NULL does not change the current seed.

show_categorical

If TRUE, marks categorical variables differently from numeric ones. Determined by the types_final slot of the obj argument.

return_network

If TRUE, the igraph network object is returned and can be plotted by the user using e.g. the interactive igraph::tkplot function.

...

Passed to plot_cor_network.

Value

If return_network is TRUE, then an igraph network object is returned that can be plotted by the user using e.g. the interactive igraph::tkplot function. Otherwise, the network object is plotted directly and no output is returned.

Details

This function is useful to estimate the correlation network of a simulation setup after the initial underlying distribution Z has been transformed to the final dataset X.
