Hi,
I have an upcoming project that will involve a large text file. I want to
1. read the file into R one line at a time
2. do some string manipulations on the line
3. write the line to another text file.
I can handle the last two parts. Scan and read.table seem to read the
whole file in at once. Since this is a very large file (several hundred
thousand lines), this is not practical. Hence the idea of reading one
line at at time. The question is, can R read one line at a time? If
so, how? Any suggestions are appreciated.
Thanks,
Walt
