Subject: [Rd] a simple suggestion for the next version of R windows
In-Reply-To: <Sea2-F34GykvlK6ZuAw000464b1@hotmail.com>

I don't see how it can work, period.  The `name of the workspace file' is
always .Rdata unless you loaded it from the RGui menu.  *Perhaps* the
suggestion was to give the working directory, but that is a different
concept.

There *is* a need to identify the window.  In either an MDI or SDI session
there can be console plus graphics windows, pagers and editors.  In SDI,
they appear as separate items (all with the same icon) on the task bar and
one does need to know which is which -- that is one of the main purposes
of the window title.   BTW, that icon is usually far from `big blue' on 
high-resolution screens and can be quite inconspicuous, especially if the 
background colour is blue (as it is in the standard XP schemes).

I suspect it is really unusual to run more than one R session in different
consoles, and when I do I know which is which from their screen
positioning.  I do more often run multiple Rterm.exe, and the same comment
applies there (they change the terminal title to `Rterm' and don't change
the icon).

What might be useful is to implement a setWindowTitle() function, which
append a string (default the current working directory?) to the title
(still keeping `R console' or `Rterm').

Finally, please do not post to both R-help-request (that's for
subscriptions etc so I guess you meant R-help) and R-devel.  There is a
specific address for comments on R for Windows, and it is in the README,
etc:

It could -- it could display the current working directory.
