I have written an introductory book with R, titled Technical Analysis with R. Readers are prepared how to do
- data manipulation (dyplr package)
- conduct econometric analysis (regression, time series),
- plotting (ggplot2 package, dygraphs package),
- webscrapping (rvest package, wbstat package, quantmod package), and
- financial analysis (quantmod package, quantstrat package).
- backtest a complex trading strategy and evaluate the performance.
The book is available through here (this website), bookdown (free online gitbook) or Gumroad (name-your-own-price offline pdf and epub). You can read the whole book through bookdown. Of course, you are very welcome to consider buying me a cup of coffee by purchasing the ebook.
After purchasing through Gumroad, you can download pdf and epub.
