Hello,
I have been getting the following intermittent error from kmeans:

Dirk and Ray have provided two very clever solutions which
perform transformation and selection in one go
by returning NA and NULL respectively for unwanted elements
and then eliminating the NAs and NULLs.
I thought it would be worthwhile to bring them together and
make some further minor

This has already been answered but I think behind your
question may have been the thought of whether its
possible to do it all at once: transformation and selection.
There are languages that do allow this. For example, Python
has list comprehensions which are things like this:
# give me
Currently the function symbols() permits plotting of circles, squares, rectangles,
stars,
thermometers, and boxplots.
Can anybody suggest an approach for extending/cloning this function to handle
arbitrary shapes specified, perhaps, as bitmaps, or as postscript primitives?

When I did it in S-Plus 6.1 and R 1.8.0, I didn't get NULL entries: I
got NAs. There is a difference between NULLs and NAs. The NAs can be
deleted using is.na, as follows:

Hi,
I'm trying to subset a list which contains variable length vectors.
What I want to do is extract (eg.) the 3rd item in each vector (with
length >= 3). At the moment I'm using sapply(list.of.vectors,
function(x) {x[3]}). The problem with this is that sapply returns a
list of the same len
Hi Dirk (and Tomomi):
Thanks for the quick reply. I tried using
'--configure-args="--with-fftw-lib=/usr/local/fftw-3.0.1"', but it did not
help. configure still fails at the same place:
...
checking for fftwnd_one in -lfftw... no
configure: error: Sorry, cant find fftw library. Please use --wit
Well!
Isn´t that what Copulas is all about.

This is strange, since the source code explicitly sorts them. Can you send
an actual exampl

Brian D. Ripley,
Well, it is one of those things
-- it works in R but not in S
-- it appears in the examples for help(":") but is not otherwise mentioned
on the help page (why?)
-- it does not give a numerical list of combinations, as asked for
-- it does give unused levels, which in this application is disastr

Cannot this be done even easier by calculating the interaction?

Hi all,
Please forgive my ignorance, but is there such thing
as a "multiple cross-correlation function", i.e., a
cross-correlation function for more than two time
series. If there is, is it implemented in R? I
couldn't find it.
Thanks,

I'm using R 1.7.1 under linux redhat
it seems that the eigen values produced by eigen() do not follow
a consistant order; I mean either ascending or discending
e.g
for one system:
eigenV<-eigen(V)
> print(eigenV$values)
[1] -7.706828e+13 -4.702980e+13 -3.267579e+13 -1.701297e+
Factor3 <- factor(unclass(Factor1) + nlevels(Factor1)*(unclass(Factor2)-1))
will give you the unique combinations, not labelled as you do but then I
don't think you need that.

This might be easy but I'm very new to R and this question doesn't seem to
have any nice keywords that bring up relevant search results when I search
