In andrie/discretizer: Discretizes values

discretizer

The goal of discretizer is to discretize data in a data frame (x and y) to a matrix for fast visualizationn

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("andrie/discretizer")

Example

To illustrate discretization, create a strange attractor with 10 million points, and the plot:

(This takes \~10 on my laptop.)

library(magrittr)
library(discretizer)
par(mar = rep(0, 4), mai = rep(0, 4))

c(-0.8, 0.4, -1.1, 0.5, -0.6, -0.1, -0.5, 0.8, 1.0, -0.3, -0.6, -0.3, -1.2, -0.3) %>% 
  strange_attractor(1e7, 1, 1) %>% 
  trim_quantiles(q = 0.05) %>% 
  discretize() %>% 
  log1p() %>% 
  recolour("BuPu") %>% 
  plot()
