Hi there,
I want to read large files line by line in order to process each line
and store the information of each list iin an object. My problem is,
that I do not know how to process each line of the file, because I
want to avoid to import the whole file.
The data file "inputdata.csv" is a CSV file with a header like:
Number, Name, factors1, factors2
"123", "some characters", "a; list; of; factors", "a; second; list;
of; factors"
How can I read the file in a manner like:
foreach_line_in("inputdata.csv") {
currentline <- function_or_command_to_get_the_current_line()
?readLines
# { here comes the block in which the current line is processed, and
the new object created
# no help needed here}
}
Thanks and regards,
d!rk
