Subject: PowerCut Killed R - is my code retrievable?
I've been tweaking code for several days on and off in R, cut and pasting in from a text editor (I just leave them open all the time). I think I got something that was usable but then a powersurge tripped the fuses and unfortunately the machine I was working on doesn't have a UPS.
Does R hold the command data in cache some place? I've purposefully not opened R since the crash so that if it did I don't over write it?
I guess what I'm wanting is the equivalent of the linux up arrow which repeats the last line. i know that exists in R but from what I recall it didn't work when you close the R session. Is that stored in a hidden file someplace that I could copy?
Its not a huge piece of code or anything - but it was code I tweaked over several stages as I'm new to R and so it was part of my learning process.
Also - is there a better way for the future? I know some people use IDE's but is that for serious programming or for building a small function and tweaking it?
Thanks
Calum
