This example visualizes the relative importance of variables from a random forest model, ranking them by their MeanDecreaseGini values and displaying the rankings as white numeric labels within a horizontal bar chart. The visualization uses `ggplot2` in R, employing `geom_bar` with `coord_flip` to create horizontal bars, and `geom_text` to overlay rank labels. Data preprocessing relies on the `dplyr` package for ranking variables via `dense_rank`, while the fill color encodes importance magnitude, making the most influential variables visually distinct.

This example visualizes the relative importance of different variables in predicting income levels using a random forest model. The code loads an income dataset from GitHub, shuffles rows, and handles missing factor values before training the model with `randomForest`. It then relies on `ggRandomForests` to plot variable importance scores, showing which predictors most strongly influence income classification. The visual output highlights the ranked contribution of each feature, with the model trained on the processed data frame.

This chart shows the relative importance of variables in a Brexit-related model, ranking them from least to most influential. The code uses R with the ggplot2 library to create a horizontal bar chart, employing `geom_col` with `coord_flip` for orientation. Data is processed through dplyr’s `arrange` and `mutate` functions, with `forcats::fct_inorder` to preserve factor order. The bars are filled in navy blue with white outlines, and the plot uses `theme_bw` for a clean background, displaying the importance scores as bar lengths.

This chart displays the relative importance of predictor variables in a linear model predicting ozone readings, using a horizontal dot plot with labels. The code loads the `relaimpo` package, fits a linear model with `lm(ozone_reading ~ ., data = Ozone)`, and calculates scaled importance metrics via `calc.relimp(..., type="lmg")`. The result is sorted and rendered with `ggplot2`, using `geom_point`, `geom_text` with a label nudge, `coord_flip`, and `theme_minimal` to show each variable’s contribution on a 0–0.3 scale.

This example shows the variable importance results from a Boruta random forest feature selection analysis, displaying which predictors are confirmed, tentative, or rejected as significant. The plot renders a boxplot-style visualization of variable importance scores, with the Boruta output object passed to the base R `plot()` function. The code first extracts the names of confirmed and tentative variables using the `names()` and `%in%` operators on the `finalDecision` vector, then prints them. The visualization uses R’s standard graphics API, with `cex.axis`, `las`, and `main` parameters adjusting label size, orientation, and title.

This example visualizes the output of a conditional inference tree model that predicts the percentage of “Leave” votes in the Brexit referendum from the training dataset `Brexit_train`. The chart displays both the tree’s internal split nodes—annotated with the chosen split variable and sample size—and terminal nodes, which include a bar plot showing the distribution of the target variable (`Percent.Leave`) as filled proportions. The visualization is built using the `ggparty` and `partykit` R packages, with `ctree()` generating the model and layered `ggplot2`-style geoms (`geom_edge`, `geom_node_label`, `geom_node_plot`) rendering the tree structure and node-level plots.

This visualization demonstrates the outcome of a classification tree model for predicting Brexit voting behavior. It displays the fitted decision tree structure, showing variable importance and split values. The example uses the R programming language with the `printcp` and `plotcp` functions from the `rpart` package to output the model’s complexity parameters and render its cost-complexity plot. The data originates from a gist by BenHeubl, with the underlying source file containing the model fitting code.

This example shows a decision tree model of Brexit-related data, visualizing the hierarchical splitting of predictor variables into classification nodes. The tree uses colored boxes with a red-to-yellow-to-green palette to indicate different outcome probabilities or class assignments across branches. The plot is generated with the `rpart.plot` function, using type 4 for a fancier layout, extra 0 for minimal node labeling, and dashed branch lines via `branch.lty = 3`. The underlying model, `Brexit_model`, is built from an rpart decision tree, and the visualization directly renders its structure without additional data processing.

This visualization shows a decision-tree model of Brexit voting patterns, mapping how various factors predict the percentage of Leave votes across the UK. The code builds a classification tree using the `rpart` function on the `Brexit` dataset, with `Percent.Leave` as the target variable. The tree’s branching structure reveals the key demographic or geographic splits that separate Remain- and Leave-leaning areas. The rendering relies on R’s base graphics to display the tree nodes and splits, while the user must supply a complexity parameter (`cp`) to control tree depth and overfitting.
