Well, you could simply source() the .Rhistory file (or the file you saved under some other name). But as you already poitned out - it's better to go with scripts to begin with. cu Philipp -- Dr. Philipp Pagel Lehrstuhl für Genomorientierte Bioinformatik Technische Universität München Wissenschaftszentrum Weihenstephan 85350 Freising, Germany http://webclu.bio.wzw.tum.de/~pagel/ __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] How to save & play back an entire R session?
Thank you all. I experimented with the various suggestions you proposed. Saving the session history is indeed easy (savehistory). The problem is the playback. I didn't find a reliable method. Plus, I now realize that the very idea of playing back a saved session is, in general, a bad one, since such a session may have made changes to disk. So I'll go with Rob's idea of working indirectly from a script that I keep re-sources. Thanks again!

Re: [R] How to save & play back an entire R session?
To just save a copy of all the commands issued you can use the savehistory function (this is documented on the same page as history, so David's answer would have lead you there as well). If you want to save all the outputs from you session you can use the sink function. You can save a combination of the inputs and outputs using the R2HTML package or the TeachingDemos package (see ?txtStart in the later). For both of those you need to start recording and end recording (and specify if you want a graph saved). The txtStart option also gives the option to save a script file of all the commands (similar to saveHistory, but as you go along rather than after the fact) that can be rerun later using source. But it is generally better to write a script file and run from that, then you have control over what goes into the file, do you really want to rerun all calls to help and mistakes? You can run a whole script from a file using the source function, or there are various editors that will send lines or blocks to be evaluated (the R gui on windows does this, also emacs, tinn-R, vim, and probably others that I missed). -- Gregory (Greg) L.

Re: [R] How to save & play back an entire R session?
Roy, In addition to previous responses, another way of achieving this is to only work from scripts. I rarely type anything directly into R, just edit scripts in an editor and then execute the entire script (or parts of the script) from within the editor. This way of working provides backup, e.g. if something goes wrong in R. Typing directly into the R session is still useful to quickly try something or help questions.

Does anyone know how to achieve this? history(Inf) will display all inputs. You could save those and cut and paste them to run again. In the Windows console (and others?) you can save the complete contents. This is just the text output. You can re-run pieces using cut and "Paste commands only" (which I think is a Windows-only option).
