Using GetDFPData2 to import Annual Reports from B3

Marcelo Perlin

2023-04-25

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.

# only in github, soon in CRAN
devtools::install_github('msperlin/GetDFPData2')

# not in CRAN, install from github
devtools::install_github('msperlin/GetFREData')

library(GetDFPData2)

# information about companies
df_info <- get_info_companies(tempdir())
print(df_info )

search_company('grendene', cache_folder = tempdir())

library(GetDFPData2)

# downloading DFP data
l_dfp <- get_dfp_data(companies_cvm_codes = 19615, 
                      use_memoise = FALSE,
                      clean_data = TRUE,
                      cache_folder = tempdir(), # use local folder in live code
                      type_docs = c('DRE'), 
                      type_format = 'con',
                      first_year = 2019, 
                      last_year = 2020)
