TEXT FILE TIME SERIES IN R HOW TO

However, the majority of R resources and documentation start with the optimistic assumption that your data has already been loaded, ignoring the fact that importing datasets into R, and exporting them to the world outside the R ecosystem, can be a time-consuming and frustrating process. Data I/O will be needed on projects where data comes from, or goes to, external sources. Input/output (I/O) is the technical term for reading and writing data: the process of getting information into a particular computer system (in this case R) and then exporting it to the ‘outside world’ again (in this case as a file format that other software can read).
