Another year has passed and now its time to discuss what happened in this cycle, along with future projects. Year 2023 passed by very quickly, and I’m grateful for everything I’ve learned and experienced. Here are the highlights from my work. Highlights of 2023 and 2022 Academic Papers I co-authored a single academic papers during this period: What is the sustainable withdraw rate for Brazil? However, many papers are ready (or almost ready) for submission. I expect that 2024 will be a year with many publications. Books I revised book Analyzing Financial and Economic Data with R for its second edition.

Back in 2020 I started to compile and share financial data in dataverse. The data covers corporate finance events from the DFP and FRE systems. The available tables are the same I use for my research and teaching material, and will be updated once a year. Today I updated all datasets. 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 2023-04-18 GetFREData CVM Corporate dataset from FRE systems Link 2023-04-18 GetDFPData2 CVM Annual Financial Reports from DFP system Link 2023-04-18

It is with great pleasure that I announce the third edition of “Analyzing Financial and Economic Data with R”. This work is an international edition of my R book and a lifelong project. My plan is to keep improving the content as much as possible over the next years. I’m happy to see that, just like good wine, the content of the book only gets better with time. Besides the usual revision and improvement of the text, here are the main changes: New pipeline operator A new pipeline operator (|>) was introduced in R version 4.

The third edition of Analyzing Financial and Economic Data with R provides a total of 98 end-of-chapter exercises. All activities are freely available in the exams format, meaning that any R tutor can export the same exercises and solutions to use in their own class. In this post I’ll show how to compile exercises to pdf, html, Moodle and blackboard. Installation The first step is to install package afedR3 with devtools: if (!require(devtools)) install.packages('devtools') devtools::install_github('msperlin/afedR3') Another requirement is a working Latex instalation. For that, use tinytex: tinytex::install_tinytex() Compiling Exercises How it works?
