Hi Jeff,
Please see my original question.
You were told that RGui is not an editor.
Are you implying that your initial message contained an implicit request
for instructions on how to get R code in an .R file to be opened
automagically when double-clicked or to have "open in <some editor>"
appear when right-clicked? (I didn't see that clearly expressed.)
If you want something else to happen with a file that has a .R extension
when double-clicked or right-clicked in a GUI file manager, then you
need to configure your OS to do whatever else it is that you expect.
This is not really an R question. It's an OS question. There are many
editors that can also bring up R consoles when the right key combo is
pressed. They do require some study for their specific actions, but this
is not really the place to get guidance on the fine details.
Friends, RGui contains an editor. It allows to send lines / code blocks
to the R concole. We know users who need braille displays use the RGui
internal editor as that apparently cooperates better with braille
displays + R as many other editors.
And as it does not hide half of R by its own functions, I'd pefer that
over some very popular other editors if I had no other choice.
To answer the OP's question, R does not have a built in way to get this
task directly done, but searching the web suggests a rather simple way
(well,m a hack as starting R with other command args may fail now, but
you can extend this and look for a specific naming scheme):
<https://stat.ethz.ch/pipermail/r-help/2007-August/138064.html>
let is adapt this for the recent version of R:
1. Add the line
if ( length(z <- commandArgs(TRUE)) ) utils::file.edit(z[1])
to the Rprofile.site file; and
2. Edit the registry to associate the .R extension with the command
C:\Program Files\R\R-4.2.2\bin\x64\Rgui.exe --args "%1"
I think we should implement this in R anyway.
Best,
Uwe Ligges
