Reproducible finance is a philosophy for doing financial analysis in a way that clear, understandable, and reproducible. The goal is to make financial analysis readable and reproducible in different coding styles and data structures. The 3 universes are : xts (time index for the order of the data), tidyverse (organizing and transforming data, used for data wrangling with the dplyr package), tidyquant (combines strengths from xts, performanceanalytics, and tidyverse to apply financial functions to tidy data frames). Data visualization is used to translated quantitative work into clear, visual graphs, which makes it more understandable for others.
