Oddities with RSiteSearch?
[If I knew who to report this to privately, I would. Sorry to embarrass
anyone who's just trying to contribute to the R-project.]
There seems to be some oddities with the RSiteSearch web page. When I
enter 'RSiteSearch("console")' I'm taken to

transition matrices
I am working with transition matrices of sequences of animal
behaviours. What I would like to do is parse the original matrices,
adjusting row/column order so that the matrix has its main values in blocks
surrounding the diagonal. This would cause behaviours involved in
functional groupings (e.g. grooming, resting, foraging etc) to appear as
blocks.
This can be done manually by applying

calculate AUC and plot ROC in R
Hi, there:
Could someone tell me a simple function of plot ROC curve and calculate
AUC in R? My setting is very simple, a column of the true binary
response and another column of predicted probabilities.
Thanks!

lme4 on Mac OS X
I have been trying to get the lme4 package installed on Mac OS X... with no
success. The Mac OS binary is not available on any CRAN, and I also canĀ¹t
install the package from old source. Has anyone found a solution to this
problem? I am happy to use nlme for now, but I tend to prefer to do my
mixed model analyses with lmer().
Thanks,

searching Jonathan Baron's R Site
First, my site will be down December 27-28 because of a network
upgrade at Penn. It will also be down at least one day before
that, while I upgrade the operating system. (And another day
some time in January because of a planned power outage.)
Second, I have replaced the search engine in my R site:

count ties after rank?
Hello!
I need to use Kruskal-Wallis test and post-hoc test (Dunn's test) for my data. But when I searched around, I only found this function: kruskal.test. But nothing for Dunn's test.
So I started to write one myself. But I do not know how to count ties in the data frame. I can use for loops but it seems long and unnecessary since the rank function actually knows the ties. So

Moving average
Good morning all!
I am attempting to superimpose a moving-average smoother onto a graph of
daily plots. These plots (in table[,2] below) span about 350 days and
looks very noisy. I'd like for this smoother to plot the average of each
group of 7 consecutive days (weekly) and show a line which joins these
series of averages. Given the definition of MA, the first and last points

The "lib" argument in install.packages().
I was flummoxed for a long time by errors generated when I did
something like
install.packages(foo,lib="Rlib")
where ``Rlib'' is my personalized directory of R packages, which
lives in my home directory (from which I started R before issuing
the foregoing install.packages() call.
Recently someone (I forget who, but thanks very much to whomever
it was) pointed out that I

Fwd: Re: RSiteSearch, sos, rdocumentation.org, ...?
Unfortunately, I am unable to get this search site working again. (The
message below explains why I had to rebuild it.)
The computer worked for the better part of a day downloading and
installing all the help files from all CRAN packages. Somehow it
failed to get the vignettes this time. But I pushed ahead and ran the
part of namazu that makes the search indices: mknmz. And you can see

.libPaths(new) stopped working in 2.10
I used to have the following in my .Rprofile:

packages there, so during an upgrade, I'd know exactly which packages

Fwd: Re: RSiteSearch, sos, rdocumentation.org, ...?
I looked at rdocumentation.org. At first I thought it was a superior
replacement for namazu, but after I tried a few things I decided that
it wasn't. I could not find any documentation about how to search, and
the various things I tried seemed to yield very strange responses,
e.g., a search for "Hayes mediation bootstrap" gave me mostly
functions that had nothing to do with the

sample size estimation for count (poisson?) data?
Is there a function in R that will allow me to estimate the sample
size required from count data (poisson data?), given the known
variance and desired margin of error and confidence interval?
My specific data set will be based on a survey of hikers that will be
asked about the number of animals of species 'x' they observed during
a given period. I need to know the number of hikers

plot.logistic.fit.fnc
Hello,
I can not get the function plot.logistic.fit.fnc() working....it
returns "Error: could not find function "plot.logistic.fit.fnc"".
Do I need to upload as specific package first? I am trying to check
the fit of a mixed logistic model.
Also, any advice for checking the assumption of independence in a
mixed logistic model?
Many thanks in advance,
