[R] Newbie Question: Repeatable Tasks
Hello mailing list, I am new to R using RStudio in Windows and I just want to have repeated tasks each day but could not find an answer to that reading a lot of intros, scrolling through even more and reading on S.O. I connect to a database, load data, do calculation, write results to the database and close connection. Can I save what I typed into the console as a script (I just figured how to type into the Source window)? My idea is to have three scripts (if scripts are the right way to do it): one for connection, second for calculation, third to close connection. Would I then call them by source(..R) or is there a click-button-solution? I would really appreciate if someone guides me in the right direction (link, tutorial, example would be sufficient).

Re: [R] Newbie Question: Repeatable Tasks
Just type the commands in the Source window of RStudioo, debug, save as a .r file and source it. I don't see any particular reason to have three scripts once everything is running correctly but you may find it useful.

Re: [R] Newbie Question: Repeatable Tasks
Thanks John, It works. (just saved source and clicked Source to run it, without debug(?)). Best Chris -Ursprüngliche Nachricht- Von: John Kane [mailto:jrkrid...@inbox.com] Gesendet: Montag, 4.

Re: [R] Newbie Question: Repeatable Tasks
Breaking up the task is an excellent way of thinking. John's solution is probably simplest in the short run but not necessarily best in the long run. How I'd do it is write a function for each of your three tasks and then have a script to call the functions. There would be two source files: one with the function definitions and one with the script. The advantage of functions is that they tend to encourage breaking up tasks, and they are more likely to be useful in more than one instance. They help achieve long-term laziness.
