In xy.coords(x, y, xlabel, ylabel, log) :
1 x value = 0 omitted from logarithmic plot
This seems to be an error since all the values in x are positive.
Thanks,

from observations (n+1) to (n+T+1). The two $\hat theta$
values should be similar to each other, hence just one or two
iterations should be required in making each step.

How would I do something like this:
f - function(x, g) {
s - as.character(g) # THIS DOES NOT WORK
sprintf(The %s of x is %.0f\n, s, g(x))
}
f(c(2,3,4), median)
f(c(2,3,4), mean)
and get the results
The median of x is 3
The mean of x is 3

lower than 1, then any sample median of these bootstrap
samples should be lower than 1. The upper cutoff of the 95% confidence
interval should also be below 1.
Is this a bug in the boot package? Or should I be using `Percentile'
or `BCa' in this situation?

Folks,
I wrote some text and code to help people think more clearly about
weight loss or weight management. This is at:
http://www.mayin.org/ajayshah/MISC/weightloss.html
I hope this is useful to others. Do tell me if there are things there
which I can improve.

R
I want to write:
zap - function(v) {
if (exists(v)) {rm(v)}
}
But of course this doesn't work because the rm() acts on v which is
within zap() and doesn't affect the parent environment:
x - 1
zap(x)
x
[1] 1
How would I make this zap() function work?

So the R is 1.5x costlier for the vector version and 425.5x costlier
with matlab.
I wonder what we're doing wrong!

it is no secret that R does badly with loops. Thats why
should by all
means use Matlab.
A good chunk of statistical computation involves loops. We are all
happy R users. I was surprised to see that we are so far from matlab
in the crucial dimension of performance.

this could be. The estimated coefficient of x is quite
different between the two cases.
There must be an interesting theoretical angle to this. I would
greatly appreciate some help in understanding this, and (more
generally) in interpreting the R2 of regressions where the intercept
is absent.

I wondered was people on this list felt about this article:

which talks about the problems of obtaining sound answers in numerical
optimisation in settings such as MLE or NLS.

paste(c(a,b,c), d)
of course yields
