The goal of rfinance is to provide a user-friendly suit of tools to perform financial analysis on R.
You can install the released version of rfinance from CRAN with:
install.packages("rfinance")Let's say that you want to download all historic prices from a given company. get_prices() will let you do just that and get it stored in a data.frame. You just need to specify the symbol. In the case of this example, Microsoft's symbol is MSFT.
library(rfinance)
df <- get_prices(symbol = 'MSFT')In most financial analysis, the financial statements released by firms are arguably the more important variables, and the harder to get.
rfinance provies a set of functions to get the different financial statements of any public company.
msft_statements <- get_statements("MSFT")At this point it'd be natural to ask yourself what companies are available for this. rfinance includes a function to check just that. get_tickers() will give you an array of all the symbols available in the API.
symbols_list <- get_tickers()
