plot_density: Plot density of numerical variables

In konradsemsch/ggrapid: Create neat & complete ggplot visualizations with as little code as possible

Description

This function creates nicely formatted, standardized density plots.

Usage

plot_density(df, x, fill = NULL, facet = NULL, position = "identity",
  ticks = 5, angle = 0, title = TRUE, subtitle = NULL,
  caption = NULL, lab_x = "Value range", lab_y = "Density",
  legend = TRUE, vline = c(NaN), alpha = 0.7, quantile_low = 0,
  quantile_high = 1, theme_type = "ipsum", palette = "awtools")

Arguments

df	A data frame.
x	A numerical variable to plot its density.
fill	Select an additional grouping variable to be used for density plotting. Defaults to NULL.
facet	Select an additional faceting variable to create facets. Defaults to NULL.
position	Select the positional adjustment of the plot. Possible values are: "identity" (default), "stack" or "fill"
ticks	Select the number of ticks on the x and y axis with the number_ticks function. Defaults to 10.
angle	Select the rotation angle for the x axis labels. Defaults to 0.
title	Should the plot title appear automatically. Defaults to TRUE.
subtitle	Text that is displayed on the subtitle. Defaults to NULL.
caption	Text that is displayed on the caption. Defaults to NULL.
lab_x	Text that is displayed on the x axis. Defaults to "Value range".
lab_y	Text that is displayed on the y axis. Defaults to "Density".
legend	Should the plot legend appear automatically. Defaults to TRUE.
vline	Should any vertical lines be added to the plot. Defaults to c(NaN).
alpha	Select plot fill transparency. Defaults to 0.7.
quantile_low	Select lower percentile for outliers exclusion. Defaults to 0.0%.
quantile_high	Select upper percentile for outliers exclusion. Defaults to 1.0%.
theme_type	Select a theme type from themes available in the apply_theme function. Defaults to "ipsum".
palette	Select a palette type with the select_palette function. Defaults to "awtools".
