Plot Coefficients of Parallel Trends — plot_coef_par

This function generates coefplots or iplots based on fixest outputs, allowing the user to visualize interaction coefficients with ease.

Usage

plot_coef_par_trends(
  data,
  dependent_vars,
  time_var,
  unit_treatment_status,
  unit_id_var,
  plot_type = "coefplot",
  combined_plot = TRUE,
  legend_position = "bottomleft",
  legend_title = "Legend Title",
  legend_args = list(),
  plot_args = list()
)

Arguments

data: Data frame containing the data to be used in the model.
dependent_vars: Named list of dependent variables to model and their respective labels.
time_var: Name of the time variable in the data.
unit_treatment_status: Name of the treatment status variable.
unit_id_var: Name of the unit identification variable.
plot_type: Type of plot to generate. Either "coefplot" or "iplot".
combined_plot: Logical indicating whether to combine plots for all dependent variables.
legend_position: Position of the legend on the plot.
legend_title: Title for the legend.
legend_args: List of additional arguments to customize the legend.
plot_args: List of additional arguments to customize the plot.

Value

A plot visualizing interaction coefficients.

Examples
