coef_plot: Plots the coefficients of FERGM and ERGM objects.
In fergm: Estimation and Fit Assessment of Frailty Exponential Random Graph Models

Description Usage Arguments Value References Examples

This function allows the users to visualize FERGM estimates or to compare the coefficients of ERGMs and FERGMs.

1	coef_plot(fergm.fit = NULL, ergm.fit = NULL, custom_var_names = NULL)

`fergm.fit`	A model object returned by the `fergm` function. Must be specified.
`ergm.fit`	A model object returned by the `ergm` function. May be specified when comparing ERGM and FERGM coefficients.
`custom_var_names`	A vector of custom variable names used in presentation that match the order of the `form` object passed to `fergm`. If not provided, defaults to names inherited by `fergm.fit`.

This function produces a coefficient rope-ladder plot containing 95% confidence intervals using ggplot2. The function either takes fergm model output or fergm and ergm model output. The former is effective in summarizing fergm model output while the latter is effective in comparing FERGM and ERGM estimates.
