advice? thanks
install.packages( "devtools" )
devtools::install_github("ajdamico/lodown")
devtools::install_github("jimhester/archive")
file_folder <- file.path( tempdir() , "file_folder" )
tf <- tempfile()
# large download! cachaca saves on your local disk if already downloaded
lodown::cachaca( '
http://download.inep.gov.br/microdados/microdados_enem2009.rar' , tf , mode
= 'wb' )
archive::archive_extract( tf , dir = normalizePath( file_folder ) )
unzipped_files <- list.files( file_folder , recursive = TRUE , full.names =
TRUE )
infile <- grep( "DADOS(.*)\\.txt$" , unzipped_files , value = TRUE )
# works
R.utils::countLines( infile )
# works with warning
my_file <- readLines( infile , skipNul = TRUE )
# crash
my_file <- readLines( infile )
# run just before crash
