GetDFPData2 is the second and backwards incompatible version of GetDPFData, a R package for downloading annual financial reports from B3, the Brazilian financial exchange. Unlike its first iteration, GetDFPData2 imports data using a database of csv files from CVM, which makes it execute much faster than its predecessor. However, the output is slightly different.
