multi_plot: Flexible Static or Interactive Plotting of Variables

Source: R/multi_plot.R
multi_plot.Rd

Generate a variety of plots—histogram, density, boxplot, barplot, violin, scatter, heatmap, or spider (radar)—either as static ggplot2 objects or interactive Plotly widgets.

Usage

multi_plot(
  data,
  x = NULL,
  y = NULL,
  plot_type = NULL,
  interactive = FALSE,
  fill_color = "steelblue",
  color = "black",
  bin_width = NULL,
  group = NULL,
  facet = NULL,
  radar = NULL,
  radar_color = "steelblue",
  radar_labels = NULL,
  radar_cex = 1,
  radar_ref_lev = "Yes",
  title = NULL,
  x_lab = NULL,
  y_lab = NULL,
  legend_position = "right",
  axis_text_angle = 0,
  axis_text_size = 12,
  title_size = 14,
  theme_custom = ggplot2::theme_minimal()
)

Arguments

data

A data frame or tibble containing your data.

x

Character; name of the variable for x-axis (required for all plot types except spider).

y

Character; name of the variable for y-axis (required for boxplot, violin, scatter, and heatmap).

plot_type

Character; one of "histogram", "density", "boxplot", "barplot", "violin", "scatter", "heatmap", or "spider".

interactive

Logical; if TRUE, returns a Plotly interactive plot (not available for spider/radar charts). Default: FALSE.

fill_color

Character; fill color for non-grouped geoms (default "steelblue").

color

Character; outline/line color (default "black").

bin_width

Numeric; bin width for histograms. If NULL, computed automatically.

group

Character; name of grouping variable (optional).

facet

Character; name of variable to facet by (optional).

radar

Character vector; names of exactly 5 variables for spider plot (only for "spider").

radar_color

Character or vector; border/fill color for spider chart (only for "spider").

radar_labels

Character or vector; names of the variables for spider chart (only for "spider").

radar_cex

Numeric; font size for variable labels in the spider chart (only for "spider").

radar_ref_lev

Character; reference level for factors included in the spider chart (only for "spider").

title

Character; plot title (optional).

x_lab

Character; x-axis label (defaults to x).

y_lab

Character; y-axis label (defaults to y or "Count").

legend_position

Character; one of "right","left","top","bottom","none" (default "right").

axis_text_angle

Numeric; rotation angle (degrees) for x-axis tick labels (default 0).

axis_text_size

Numeric; size of axis text in pts (default 12).

title_size

Numeric; size of plot title text in pts (default 14).

theme_custom

A ggplot2 theme object (default theme_minimal()).

Value

A ggplot object (if interactive = FALSE or plot_type = "spider") or a plotly object (if interactive = TRUE).

Details

  • Histogram: requires x; uses geom_histogram(). Use for continuous numeric variables only.

  • Density: requires x; uses geom_density(). It should be numeric.

  • Boxplot/Violin: require both x and y; automatically groups by x or by group if provided, with dynamic dodge width.

  • Barplot: requires x; counts occurrences. Use for categorical variables only.

  • Scatter: requires both x and y; uses geom_point(). Both variables must be numeric.

  • Heatmap: requires both x and y. Both variables must be categorical.

  • Spider: requires radar (vector of variables); uses fmsb::radarchart(), static only.

Examples


multi_plot(icu,
  x = "icu_enter_days",
  y = "vent_mec_start_days",
  plot_type = "scatter",
  color = "darkred",
  title = "ICU exit vs MV days"
)
#> Warning: Removed 5330 rows containing missing values or values outside the scale range
#> (`geom_point()`).


multi_plot(
  comorbidities,
  radar = c("hypertension", "dyslipidemia", "depression", "mild_kidney_disease", "dm"),
  radar_color = "steelblue",
  radar_ref_lev = "Yes",
  plot_type = "spider"
)
