The bigger issue is that R can't tell the location of an open script, which makes it harder to create new versions of existing work....But it can. If you open a script and choose save, it will be saved to the same place. Or do you mean an executing script? There are indirect ways to find the name of the executing script. For example, in R-devel (to become 2.13.0 next month), you can do this: cat("This file is ", getSrcFilename(function(){}, full=TRUE), "\n") The getSrcFilename() function will be new in 2.13.0. You can do the same in earlier versions, but you need to program it yourself.Could getSrcFilename() gain a default argument so that getSrcFilename() would by default return the path of the executing script?
No, it needs to see a function defined in that script.
