failed creating protocol instance to play queued url
I run thunderbird (both 3.x and 5.x) against dovecot 2.x and frequently
see delays "loading message". I admit to having a very large mailbox and
running multiple imap clients.
I've turned on thunderbird debugging, and at least one pattern I see in
the log during the delays (maybe a minute long) is the failed protocol
message above. These are no the only delays, but are the ones

R and Epi Info
Hello,
I was wondering who to contact to see about somehow interconnecting or integrating the programs R and Epi Info. I have been involved in the development of Epi Info which is a software program developed by the Centers for Disease Control and Prevention (CDC) in Atlanta (www.cdc.gov/epiinfo<http://www.cdc.gov/epiinfo>). Epi Info allows for creating data entry systems and performs

arrays of lists in R ("cell arrays" in Matlab)
Dear all
I would like to have some data in the form of a 2-dimensional array
(matrix) of lists, so that I can easily find the desired list object by
indexing the structure by rows and columns. In matlab there exists a
data type called "cell array": a matrix of "cells", which are composite
objects very similar to R lists.
I know that in R you can create 1-dimensional

power in a specific frequency band
Dear R users
I have a really simple question (hoping for a really simple answer :-):
Having estimated the spectral density of a time series "x" (heart rate
data) with:
x.pgram <- spectrum(x,method="pgram")
I would like to compute the power in a specific energy band.
Assuming that frequency(x)=4 (Hz), and that I am interested in the band
between f1 and f2, is the

Post-hoc t-tests in 2-way repeated measure ANOVA
Hi all
I am running a 2-way repeated measure anova with 1 between-subjects
factor (Group=treatment, control), and 1 within-subject factor (Time of
measurement: time1, time2). I extract the results of the anova with:
summary(aov(effect ~ Group*Time + Error=Subj/Time, data=mydata))
Now, this must be clearly a dumb question, but how can I quickly extract
in R all the post-hoc t-tests for the

anova() for nlm or nls
Dear R community,
I am currently fitting non-linear models using nlm and nls.
1) I would like to compare the different models analogous to the
comparison of linear models with anova(). Is there a function in R which
allows to do that?
2) I would like to constrain the parameter ranges to positive values
only. Is there an option in nlm or nls which allows to constrain
parameter ranges? (So far I

R performance--referred from Bioconductor listserv
Hi, all--
I wanted to start a (new) thread on R speed/benchmarking. There is a
nice R benchmarking overview at
http://www.sciviews.org/other/benchmark.htm, along with a free script so
you can see how your machine stacks up.
Looks like R is substantially faster than S-plus.
My problem is this: with 512Mb and an overclocked AMD Athlon XP 1800+,
running at 588 SPEC-FP 2000, it still takes me

Fastest way to repeatedly subset a data frame?
Hi -
I have a data frame with a large number of observations (62,000 rows,
but only 2 columns - a character ID and a result list).
Sample:

> my.df
id result
1 ID1 1
2 ID2 2
3 ID3 3
I have a list of ID vectors. This list will have anywhere from 100 to

integration of a discrete function
Dear R list
I am looking for a function in R that computes the integration of a
discrete curve, such as a power spectrum, in a specified interval (in my
case, that would be 'power in a certain frequency band'). I found only
functions, such as 'integrate', that perform adaptive quadrature on
analytic functions, and not on a curve specified as a set of (x,y) pairs.

I would like to connect my GHA-system to R and to deliver the

could you give me a comprehensive example containing the step by step

Errors on EXT3 on RHEL3, Can we use e2fsprogs 1.36?
SUMMARY
We are getting many ``Free blocks count wrong for group'' errors when
running e2fsck on a 245-GB ext3 filesystem. This is when the file
system is cleanly unmounted on a relatively quiet system to do a
resize. From reading other messages here, my suspicion is that this
is because we have e2fsprogs 1.32.
Questions:

While I agree that we cannot agree on the ideal algorithms, we should be

dist() objects with NA's don't print them (PR#4866)
The print.dist() method in the mva package currently prints the
triangular distance matrices with the ``trick'' of setting the
(diagonal and) upper triangular part to NA, and then uses
print(mat, na = "") to print that matrix.
This is very much undesired if there are true NAs.
Reproducible example code:
(x <- cbind(c(1,NA,2,3), c(NA,2,NA,1)))
(d <- dist(x)) ## does not
