# 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](/images/rrenko_modern.png)

    renko(df, 5, style = "classic") + 

        labs(title = "Renko chart with R", x = "", y = "")

![rrenko classic](/images/rrenko_classic.png)

## Changelog

### 0.2.0 - 2018-12-15

* Added variable `points = TRUE` that adds the last close of one date as a geom_point

* Bug fixed where data table was not recognized

* Removed modularization due to bugs

### 0.1.3 - 2018-12-13

* Works in most cases except really and really small sizes.

* x-axis labels get repeated. This will get fixed at some point.

* `renko()` funtion expects specific variables names at the moment.

### 0.1.0 - 2018-12-13

* Still unstable.

* Lots of bugs.

* For experimental use only.
