Re: [R-SIG-Mac] Retrieving Script Path in R.app
See https://stackoverflow.com/a/47045368/2554330 for a risky-looking method.
I think the non-RStudio method is equivalent to this function:
this.path <- function() {
sys.frame(-5)$srcfile
}
which works for me using Cmd-E, but of course it doesn't work using
Cmd-Enter, because that doesn't call source().
My conclusion would be to use RStudio rather than the R.app editor. I
prefer R.app for interactive use, but not at all for code development.

Hello,
I'd like to programmatically retrieve the path of the currently open script
in R.app.
Something like, if I had written:
this.path()
within a script that was open in R.app, and I ran that line with
Command+Enter,
I'd like it to return the path of the script.
It seems like this should be possible since Command+E runs the following:
source("/absolute/path/to/file")
so R.app knows the path of the open script, but I was unable to find
anything that would retrieve it on my own. First, I tried looking through
the environment 'as.environment("tools:RGUI")', but I didn't find anything
that looked like what I was looking for. Second, I tried comparing the
functions available in the base packages between Windows and macOS, and
while there are a few functions available for macOS that are not for
Windows, none of them looked like what I was looking for.
Any help will be greatly appreciated, thank you!

Andrew Simmons

Re: [R-SIG-Mac] Retrieving Script Path in R.app
getSrcDirectory is fine, but it only works when using 'source' with
'keep.source = TRUE', so it severely limits how I can run my scripts.
I've made a function / / package called this.path which returns the path of
the executing script, and right now it works from Rscript, when using
source, when running in RStudio, and when running from Rgui on Windows, but
not in R.app on macOS. Similar idea to getSrcDirectory, but you can run it
any way with or without keep.source

Hi,
Would ?getSrcDirectory help?

You may want to look at the “here” package.
