I think this is a result of the fact that Rgui doesn't use a standard
Windows control for the console, it uses a really old toolkit (a 1998
version of Graphapp). But I had never noticed the particular flaw
you're talking about: when I'm typing I mostly use the keyboard, not
One way in which I like Rgui better than R.app: you can copy prompts
and all, and paste just the commands, e.g. I could copy the lines
> x <- paste("a",
and not have to edit out the prompts before pasting into the console.
(Use "Paste commands only".) On the other hand, R.app treats pasted text
as a unit, so it's easier to scroll back a block at a time. I don't
like the way R.app lets the cursor go to places where input isn't
allowed: it means the arrow keys mean different things depending on
what you've done recently (e.g. click on the line above the input line,
and up arrow moves the cursor up; but if you move it down to the input
line, then up arrow scrolls through the history).

I'm not sure what you mean by this: what sort of things do you want?
There's no data browser, but other than that (and I admit it's a big
omission) most of what I see in the menus seems to have Windows equivalents.

I agree with this. Thanks Simon and Stefano. It's great to have some
active GUI development going on.
