gglinedensity

The goal of gglinedensity is to bring the DenseLines algorithm to R via ggplot2, providing a “derived density visualisation (that) allows users both to see the aggregate trends of multiple (time) series and to identify anomalous extrema” (Moritz and Fisher, 2018).

Installation

You can install gglinedensity like so:

install.packages("gglinedensity")

You can install the development version of gglinedensity like so:

# install.packages("pak")
pak::pak("hrryt/gglinedensity")

Example

This is a basic example which shows you how to solve a common problem:

library(ggplot2)
library(gglinedensity)
ggplot(txhousing, aes(date, median, group = city)) +
  stat_line_density(bins = 50, drop = FALSE, na.rm = TRUE) +
  xlim(2000, 2015)
