Sorry, the previous had a bug and was quite ugly. This is a bit better:
--
function (x, y = NULL, type = p, xlim = NULL, ylim = NULL,
log = , main = NULL, sub = NULL, xlab = NULL, ylab = NULL,
ann = par(ann), axes = TRUE, frame.plot = axes, panel.first = NULL,
panel.last = NULL,
It is really strange that the delayedAssign is evaluated in the environment
it is called from, and thus can have side effects.
so
x=2
y=3
delayedAssign(x, {y - 7; y+3})
gives
x
[1] 10
y
[1] 7
Both x and y changed.
More intuitive would have been the behavior
x=2
y=3
delayedAssign(x, local({y -

which only changes x.
That is questionable - I think it is more logical for both environments to
be the same as default. Just think if it -- the point here is to access

I have also often longed for such a shortcut.
The problem is that most often, my plot statements do not look like this:
plot(y)
but instead like this:
plot( some_very_long_expression_involving(x),
some_other_very_long_expression_involving(x) )
And since I'm working with a GUI, I often go up and
I'm replying here to quite an old thread started by me.
I think the dimnames facility is underused in R.
I'm currently using a 5-dimensional array. It is quite cumbersome to have to
write
y[0]
Since the array does have dimnames, I would like to be able to say instead
y[tree=0]

I wrote the interface between R and TeXmacs. Recently, I added tab
completion. However, there is one slight problem. In order to enable easy
interaction with R, I (I.e. my program) interact with the command-line
interface. This means that the user can invoke demo(), and then R will
interact with
Another message about the R to TeXmacs interface.
1. Graphics
The TeXmacs interface allows the user to directly insert graphics into the
session.
Since I am not very familiar with programming for R, I implemented the
interaction with graphics in a very primitive way. It was two modes of

The problem is this: the way I implemented tab completion is calling an R
function that creates the completion. But, while in the middle of user
input, I can't call

I don't know the mechanics of the actual inserting in TeXmac but it
would be trivial to simply create a copy of the plot as EPS (or whatever
is needed) at the time of insertion. See dev.copy2eps() for a function
that does exactly that.
Great. It works much

It doesn't really matter where the R is as long as you have some way of

exactly you do (technically) so there is not much detail we can provide...
Sorry, I'll try to provide more detail:
