The available data are: R Package Source of Data Description Direct Link Last Update GetTDData Tesouro Nacional Prices and yields of brazilian sovereign bonds Link 2022-04-06 GetFREData CVM Corporate dataset from FRE systems Link 2022-04-06 GetDFPData2 CVM Annual Financial Reports from DFP system Link 2022-04-06

Package BatchGetSymbols facilitates importation of Yahoo Finance data directly into R and is one of my most popular R packages, with over 100k installations since conception (around 2500 downloads per month). However, I developed BatchGetSymbols back in 2016, with many bad structural choices from my part. For years I wanted to improved the code but always restrained myself because I did not want to mess up the execution of other people’s code that was based on BatchGetSymbols. In order to implement all the breaking changes and move forward with the package, I decided to develop a new (and fresh) package called yfR.

Hadley Wickham recently released an online version of Mastering Shiny. The book is great! If you haven’t read it, do it fast! On a side note, it is really amazing how much of good and curated content you can get for free in R. When I started programming back in 2007, the first step was buying a brand new – and sometimes expensive – book about the language. There were blogs and other sites, but most content was very basic and not curated, meaning that the posted code most of the time did not work.
