calculating of linkage-disequilibrium measures?
Hi ,
is it possible to calculate ld-measures D, D', r and
perhaps corresponding p-values with r IF THE
PHASE IS KNOWN?
The genetics - package provides the LD function
only for ambigious phase.
Thank you very much

Data set BregFix in package flexmix
Dear list:
I would like to recreate how the artificial data set BregFix was generated

thoroughly described in Grun and Leisch's Computational Statistics & Data
Analysis 51(11) :5247-5252 but references to the appropriate seed number(s)
are missing (providing these details was certainly beyond the scope of the

betareg question - keeping the mean fixed?
Hello,
I have a dataset with proportions that vary around a fixed mean, is it
possible to use betareg to look at variance in the dispersion parameter
while keeping the mean fixed?
I am very new to R but have tried the following:
svec<-c(qlogis(mean(data1$scaled)),0,0,0)
f<-betareg(scaled~-1 | expt_label + grouped_hpi, data=data1, link.phi="log",

findFreqTerms vs minDocFreq in Package 'tm'
I am using 'tm' package for text mining and facing an issue with finding the
frequently occuring terms. From the definition it appears that findFreqTerms
and minDocFreq are equivalent commands and both tries to identify the
documents with terms appearing more than a specified threshold. However, I
am getting drastically different results with both. I have given the results

percent sign in plot annotation
Hello,
I would like to annotate a graph with the expression 'alpha = 5%' (the
alpha should be displayed as the greek letter).
I tried
> text(1,1,expression(alpha == 5%))
which gives a syntax error.
escaping the percent sign (\%) or doubling (%%) does not help.
What do I do?
Thanks,
Martin Keller-Ressel

bayesmix - What is or where can I find JAGS executable?
Hallo!
I want to use the package bayesmix. Trying the
examples I had no success. The reason is, I think:

[1] FALSE
Have read of JAGS executable (I could not find
JAGS.exe in my R directory). What is JAGS? Where can I
find or download it?

distance method in kmeans
I am trying to cluster some binary data using k-means . As the regular "kmeans" available from stats package in R does'nt provide the option to change the distance method. I was wondering there is any package available to specify type of distance measure to be used in k means clustering in R. Especially distances like "Jaccard" which is good for binary data.

model based clustering with flexmix
Hello all,
I am trying to fit a truncated mixture model and I wrote a driver for
flexmix following the example in the vignette, but it doesn't work for
me: it assigns all data points to one component only, e.g.:

> Call:
> flexmix(formula = x ~ 1, k = 2, model = truncatedmodel(lower = -4,

seqinr-dist.alignment?
Hi everyone
I have got a quick question:
I the "seqinr" package:
*dist.alignment(x,"identity")*
This is calculating the square root of pairwise distances. Does anyone know
whether/how gaps are counted in this function?
Thank you.
Best wishes,
Bettina
