Description

This function creates nicely formatted, standardised density plots.

Usage

plot_density(df, x, fill = NULL, facet = NULL, ticks = 10,
  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 = 0.025,
  quantile_high = 0.975, palette = "cartography",
  theme_type = "grey")

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
ticks	Select the number of ticks on the x and y axis. 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 .5
quantile_low	Select lower percentile for outliers exclusion. Defaults to 2.5%
quantile_high	Select upper percentile for outliers exclusion. Defaults to 97.5%
palette	Select a color palette from colors available in the select_palette function or provide your own as a nammed vector
theme_type	Select a theme type from themes available in the aider_theme function

Examples

data <- recipes::credit_data %>%
  first_to_lower()

data %>%
  plot_density(x = time)
