Visualizing Model Comparison with ggplot2 in R for Machine Learning Models
Step 1: Extract model data using sjPlot We start by extracting the model data using sjPlot::get_model_data. This function takes in a list of models, along with some options for the output. In this case, we’re interested in the estimated coefficients, so we set type = "est". mod_data <- lapply(list(mod1, mod2), \(mod) sjPlot::get_model_data( model = mod, type = "est", ci.lvl = 0.95, ci.style = "whisker", transform = NULL )) Step 2: Bind rows by model We then bind the results together using dplyr::bind_rows.
