R 2.8.0 qqnorm produces error with object of class zoo?
Dear list-reader,
by running the following script:
library(zoo)
sessionInfo()
search()
packageDescription("zoo")
data(EuStockMarkets)
dax <- as.zoo(EuStockMarkets[1:10, "DAX"])
daxr <- diff(log(dax))
identical(as.vector(qnorm(daxr)), qnorm(coredata(daxr)))
qqnorm(coredata(daxr))
qqnorm(daxr)
qqnorm() produces an error:
> qqnorm(daxr)
Fehler in if (xi == xj) 0L

qplot in ggplot2 not working any longer - (what did I do?)
This is the first time that I have tried to update packages with a
tinkered around with .Rprofile. I start R with R --vanilla and it
does not load my .Rprofile, but when I issue the command
update.packages() R downloads the packages as expected, but then seems
to load .Rprofile before compiling the packages sources. What am I
doing wrong?
kindest regards,

as.day() Function (zoo question)
I am was going to look at the as.yearmon function in the zoo package
and write a as.day function to aggregate a time series of 96
observations per day into the mean for each day, but I don't know how
to look at the code so that I can convert it into something I can use.
On top of that I believe that it is probably an S3 method and I
haven't quite gotten that far in my programming

can't merge zoo ojects and convert to ts (been trying for 2 days)
I'm stuck, but am sure it can be done I just don't understand how.
I have data in an irregular timeseries. I want to be able to use stl to
visualise the data (see seasonal parts etc), so I need to change to regular
series of class ts (I think).
I am using 2 zoo objects one is regular and the other is my irregular data.
I am then merging to create the object I want but when I try to change

chron and R 2.8
has anyone had problems with the upgrade to R 2.8 and chron date
classes. I have a large zoo object that has a chron index, and it is
taking 5x or so longer to do the same calculation as with 2.7 if it
doesn't fail. I will provide anything necessary I am not entirely
sure what ya'll would need if anything to try and reproduce the
behavior. I am using the package StreamMetabolism.

reshape bug?
Hadley et al.,
I was using the cast function to reshape some data (aggregate a melted
data frame) and I did not put in the fill and for the most part the
values that came out were fine, but there were value great than an
order of magnitude from the actual value. When I put in the fill
argument everything is okay. I don't provide a reproducible example
because the data set is to large to post

Conversions From standard to metric units
I am starting to use R for almost any sort of calculation that I need.
I am a biologist that works in the states, and there is often a need
to convert from standard units to metric units. Is there a package in
R for this already? If not I believe that I am going to write some of
the most often used in function form. My question is should I include
this in my StreamMetabolism package. It is

error when installing rjags
Hi All: I get the following error when trying to install the rjags package.
I've installed the
jags software and I'm using Fedora 10.0 and my sessionInfo is at the bottom

I'm also sorry if this email ends up having control A's all over it. I still
haven't figured how to fix that. Thanks.

Sweave:Figures from plot (LME output) not getting generated (pdf or eps)
Hi,
I seem to be facing a strange problem when I use Sweave for creating a
LaTeX document of the R lme() output --- The EPS and PDF figure files
get created, but are empty. I have attached a reproducible example

How to join path with arguments
Hi, all
How to format and join strings ?
For example, like following short python examples.

name1 = 'sample-plot'
filename = '%s.png' % name1
inputdir = '/path/to/dir'
os.path.join(inputdir, filename)

non-parametric Anova and tukeyHSD
I have insect data from twelve sites and like most environmental data
it is non-normal mostly. I would like to preform an anova and a means
seperation like tukey's HSD in a nonparametric sense (on some sort of
central tendency measure - median?). I am searching around at this
time on the internet. Any suggestions, books, etc. would be greatly
appreciated.

Problems with rbind
Dear R Users,
A recent update on base packages on my R installation has introduced a
problem to my code which did not exist before the update. The offending
function is rbind, which fails where it was working just fine before the
update.
I have two zoo objects, foo and bar, indexed by class Date. foo starts
from "2007-10-09" and bar from "2007-10-10". I attempt to pad
