NaN with ccf() for vector with all same element
hello,
i have been using ccf() to look at the correlation between lightning and electrogamnetic data. for the most part it has worked exactly as expected. however, i have come across something that puzzles me a bit:
> x <- c(1, 0, 1, 0, 1, 0)
> y <- c(0, 0, 0, 0, 0, 0)
> ccf(x, x, plot = FALSE)
Autocorrelations of series 'X', by lag

path for source()
hello,
i have a couple of .R files distributed about my file system. i commonly source() these from other files, but i have to include the full file path. this is not always convenient if you move files around. is there a way of setting the search path for source()?
thanks a lot!
cheers,

Off topic: nonparametric regression
Hi All,
What do you consider to be the best book(reference) on nonparametric regression?
I am currently reading the book of Kunio Takezawa(2006): "Introduction to nonparametric regression".
Is the book of Hardle(1990): "Applied nonparametric regression" better? or maybe another book?
This is off topic, but most of the books is using R or S-plus.
Thanks

Create factors in R for more than one variable
Hi all,
I'm using R2.0 on linux.
I have fixedwidth data consisting of 50 questions on a likert scale. The raw data is coded 1 to 5. I used read.fwf() to read in the data.
The problem is that factors isn't created automatically, because the data is coded numerically.
To make factors out of the 50 questions I must do:
V1 <- factor(V1)
I don't want to do it 50 times. Is there a

aov problem
I am using R to make two-way ANOVA on a number of variables using
g <- aov(var ~ fact1*fact2)
where var is a matrix containing the variables.
However the outcome seem to be dependent on the order of fact1 and fact2
(i.e. fact2*fact1) gives a slightly (factor of 1.5) different result.
Any ideas why this is?
Thanks for any help

library(car) Anova() and Error-term in aov()
Dear all,
Type III SS time again. This case trying to reproduce some SPSS (type III)
data in R for a repeated measures anova with a betwSS factor included. As I
understand this list etc, if I want type III then I can do
library(car)
Anova(lm.obj, type="III")
But for the repeated measures anova, I need to include an Error-term in the
aov() call (Psychology-guide from Jonathan Baron)

comparing ARIMA model to data
hi,
i am trying to teach myself about ARIMA models. i have followed examples
from a number of sources and have more or less got the hang of how it
works. i would like to compare the output from the fitted model to the
original data. is this possible? or even a meaningful thing to do?
to be clear, for example, having generated a fit to some data using
> fit <- arima(LakeHuron, order = c(1,

Hi list.
Has anyone used any commercial or open source application to integrate
Asterisk into MS Outlook 2003 which can be used to place calls directly
to contacts from Outlook?
And if so how well does it work?
Thanks,

[LLVMdev] Backend optimizations
Hi,
I'm writting an intrinsics for the X86 plateform that replace every
'call' instruction by a 'push ret_addr' followed by a 'jmp func_addr'.
I'm doing this in the X86ISelLowering class with a custom inserter.
So if I have something like this:
0x0 call foobar
0x1 ...
the call will be replaced like this:
0x0 push 0x2
0x1 jmp foobar_addr
0x2 ...
This works fine

lines and points without margin
hi,
i am sure that this is a trivial question but i have not been able to
find an answer by searching the mailing lists. i want to plot points on
a graph, joined by lines. the command that i am using is
points(x, y, type = "b", pch = 21)
this plots nice open circles at the data points and draws lines between
them. however, the lines do not come all the way up to the edge of the

scale caption on levelplot
hi,
i am trying to figure out how to put a caption on the colour scale of a
levelplot. there does not seem to be an option for this in levelplot().
i tried using mtext() but as soon as you put the text far out enough on
the right of the plot, it goes beyond the plot boundary. so i tried to
extend the margin on the right of the plot using par(mar) but this did
not have any effect on the plot area.
