R-beta: purpose of n in identify() function?
I think I am misunderstanding something about the identify() function.
if we have an example such as this:
> x_1:10
> y_1:10
> plot(x,y)
> identify(x,y, n=1)
[1] 2 3
>
I clicked on two points and identify() returned both of them (2 and 3).
The manual says n is the maximum number of points to be identified.
If I specify n=1, should identify() return a single value?

R-alpha: lbeta, ctrl-C and crashes
1. lbeta and beta do not work properly: lbeta returns its first
argument and beta gives the lbeta result.
In names.c lines 245-6, the codes for these should be 2 and 3 instead
of 1 and 2
2. crtl-C does not work (except the first time) on Red Hat elf Linux
(which has many many other problems as well) nor on the previous
version of Linux for Amiga. It worked on Slackware aout Linux and now
works

Both of these used to work and seem useful and harmless:

R-beta: lmsreg
Does R have a function like the S(plus) function, lmsreg, Least Median
of Squares Regression? I am using R-0.61.

R-beta: question on dyn.loaded code
Hi,
when designing libraries for R, is it possible to call C/Fortran
subroutines from other dynamically loaded code?
The following example crashes R:
********* fn1.c *****************
void twice(int *i)
{
*i = 2 * *i;
}
*********************************
********* fn2.c *****************
extern int twice(int *i);
void negtwice(int *i)
{
*i = -1 * twice(i);
}

R-alpha: R-W95
Seems to be working very nicely (and what a relief to see it actually
working!), I've found only a few problems till now:
a) Characters outside 0-0x7f seem to get encoded as CP850 or
something, not Latin 1 (æøå keys on DK keyboard gives
mu,degree,sigma).
b) Infinite recursion crashed R. (I forget details, but it was
something stupid like f<-function(x){if (x < 1) 1 else f(x)*(x-1)})

R-alpha: write()
Following my posting of a write.table() function, Martin suggested that
one could have a generic write() function and special methods for
e.g. time series, data frames, etc.
Well, a month has passed since ...
What does everyone think? Is it a good idea, or would write.table() be
enough? If we think that it is not enough, which arguments should the
write methods typically allow? What about

R-alpha: Equations in Plots
Paul Murrell and I are making some progress with making mathematical
expressions available in graphs. The idea is to use R expressions to
represent the mathematical expressions. So far we have (or will soon
have):
R LaTeX
x^i x^i
x[i] x_i
alpha \alpha
Alpha \Alpha
hat(x) \hat{x} \widehat{x}
bar(x) \bar{x} \overline{x}
x+y x+y
x-y x-y
x/y x/y
(x) (x)
{x} {x}
frac(x,y)

Can you confirm this problem :
###--------- RESHAPING x11() window has more problems: ----

##-- now RESHAPE the x11() - window !

R-alpha: bugs generally
In the future (say after release 0.5 goes out), would it be feasible to
start a publically-accessible list of bug reports, known bugs, and
patches? (Something like the current TASKS list, but maybe a little bit
more dynamic?)
