Reading all the lines at a time is possible but can be ricky so to process the line one at a time for reading, we can do the following

processFile = function(filepath) {

connection = file(filepath, "r")

while ( TRUE ) {

lines = readLines(connection, n = 1)

if ( length(lines) == 0 ) {

break

}

print(lines)

}

close(connection)

}
