rrenko

About

rrenko is an in-development R package to efficiently build Renko charts with the help of ggplot2 and data.table. Renko charts are used to filter the signal from the noise in volatile stock movements.

Installation

devtools::install_github("RomanAbashin/rrenko")
library(rrenko)
library(ggplot2)
library(data.table)

Variables

renko(df, size, style)
  • df = a data frame or data table with 2 variables: date (x-axis) and close (y-axis)
  • size = the size of the renko bricks (default = 10)
  • style = the visual style: modern or classic (default = "modern")

Examples

Data

set.seed(1702)
df <- data.frame(date = seq.Date(as.Date("2014-05-02"), as.Date("2018-05-04"), by = "week"),
                 close = abs(100 + cumsum(sample(seq(-4.9, 4.9, 0.1), 210, replace = TRUE))))

Code

devtools::install_github("RomanAbashin/rrenko")
library(renko)

renko(df, 5, style = "modern") + 
    labs(title = "Renko chart with R", x = "", y = "")

rrenko modern

renko(df, 5, style = "classic") + 
    labs(title = "Renko chart with R", x = "", y = "")

rrenko classic
