Dear Friend and distinguished R gurus,
first of all really thank you very much for the marvellous tool that is R.
I am using R 2.5.0, windows XP - italian language.

I don't get your point, because
exp(-(-3)^2.2)

is correct. A negative value to the power of a non-integer is undefined
in IR. Of course it is defined as a complex number:

Dear R-list,
I'm not sure what I've found about a function in DAAG package is a bug.
When I was using cv.lm(DAAG) , I found there might be something wrong with
it. The problem is that we can't use it to deal with a linear model with
more than one predictor variable. But the usage documentation
The version 2.5.0 has left Alpha status long time ago and its final
version has been released so please try the new version.

Consider the following lines of code:
plot(function(x) sin(cos(x)*exp(-x/2)), from=-8,to=7,xlim=c(-5,5))
Uses integral points (integers from -5 to 5) to draw the plot, instead
of the usual default of n= 101 equally spaced points (from
?plot.function).

Hi Patrick,
Not sure what the problem is from your email. Can you send a code
example which reproduces the error? Make sure you mention the version of
R you are using!
Also send your question/reply to/cc R-help as well. Then the rest of the
world is there to help you too.
Greetings,
Sander.
Please post general R help questions to the R-help mailing list.
The likely problem here is that your file isn't in the current working
directory. To avoid this problem, I often use the file.choose()
function to obtain a full path to the file, rather than typing the name
out myself.

Library gmodels include a function CrossTable that is useful for
crosstabulation. In the help, it is indicated that one can call this
function as CrossTable(data), were data is a matrix. However, when I try
to use this option, it doesn't help. Any idea? Is there a bug?
Thanks for your help.

Hi
I used R for the first time yesterday. I wanted to plot the aliasing
effect of sampling a 5.5KHz sinusoid at only 8KHz (below the Nyquist
limit). So I wrote a small R script that a) plots 1msec worth of a
5.5KHz sin wave b) plots 1msec of the resulting 2.5KHz alias and c)
plots the 8 sampling
Your error:
If you use plot(), the coordinate system of user coordinates is set up
each time, but you do want to plot in the coordinate system of your
first plot, hence use:
plot(time, signal, type = l, col = blue, xaxs = r, yaxs = r,
xlab = Time (msec), ylab = Signal, main = Aliasing,
That also works and is even more concise.Many thanks,
Paul

This 'strange behaviour' manifest itself within some quite complex
code. When I created a *very* simple example the behaviour dissapeared.
Here is the simplest version I have found which still causes the strange
behaviour (it could be quite unrelated to the boot library, however).
There's something peculiar that I do not understand here. However, did you
realize that the thing you are assigning into parts of `a' is NULL? Check
you're my.test.boot.ci.1: It's NULL.
Be that as it may, I get:
a - data.frame(matrix(1:4, nrow=2), X3=NA, X4=NA)
a
X1 X2 X3 X4
1 1 3 NA NA
This seems to have more to do with NULLs than NAs. For instance:
a - data.frame(matrix(1:8, nrow=2))
a
X1 X2 X3 X4
1 1 3 5 7
2 2 4 6 8
a[a$X2 == 4,]$X1 - NULL
a
X1 X2 X3 X4
1 1 3 5 7

default LINPACK qr, but incorrect (=3) using LAPACK. This is running on Linux Redhat
