Hello Paul,
thank you very much for this report. You caught a bug in R2WinBUGS that
was introduced by me. I added support for winepath in 1.1-1 version.
Since I switch between Windows and Linux I always set WINEPATH and then
use it in bugs(). That's why I forgot to add it in further calls in
CRAN et al.,
I would like to add an extented introduction or other arbitrary
sections to my package lmomco.
I have been shipping inst/doc/Introduction.Rd. I would like to have
this content inserted to the front of the PDF build for the CRAN. The

If your package is called mypkg you could create a mypkg-package.Rd
file. e.g.
library(dyn)
library(help = dyn) # note that mypkg-package is listed
package?dyn
?dyn-package # same
and you could add one or more vignettes, e.g.
library(zoo)
library(help = zoo) # note that the 2 vignettes are
I have a variable containing a measurement of a duration in seconds
which I would like to use in a plot, with the axes labelled in a format
like %H:%M:%S (or possibly %Hh%Mm) if the duration is more than an hour,
or just %M:%S if more than a minute, or just decimal seconds if short
enough. Is
Hi,
I'm looking for help on how to use R for making simple decision trees to
calculate EMV's, in a manner similar to the method applied in the
PrecisionTree add-in for Excel. Say, what is the optimal action, if:

Thanks for the help. I have found out that EBImage is an undergoing project
for building an interface from R to most ImageMagick functionality plus
additional image processing capabilities added by Oleg Sklyar (the
maintainer). You can get it from
The times class in chron will give hours and minutes. e.g.
library(times)
plot(times(0:23/23), 0:23)
and you could modify chron:::axis.times for the others.

Dear R users, I am interested in clustering in R. In SAS we have some criteria
for determining the number of clusters using the PROC CLUSTER procedure, which
are CCC cubic clustering criterion (Sarl 1981), Psuedo F (PSF), and Psuedo T
square (PST). My question is do thsese criterion exists in
Thank you very much. With the insertion of WINEPATH declaration, then
the following example program does run. And really fast, too!

Hi. I am starting to learn R for a course project. I
am relative OK c++ programer. I found the R is very
different. I have read the an introduction to R. I
have to say it is not very newbie friendly. It does
not explain many things clearly. And unfortunately,
there is not too much

I'm trying to install R-GUI on my Mac OSX, but for some reason it is

it seems to not be recognizing.

I have a big data.frame with abou 20 column and 60,000
rows for analyze. Let us say I had a column a. I
want to generate a new column which value should be
the average of the 60 a before the current column.
Let us say very row is time t_i. I need to calculate
Look at

?embed
rollmean in the zoo package
running in the gtools package
runmean in the caTools package
The last one is probably the fastest.

Hi
I am trying to get a table of means of parameter 1
across BINS of parameter 2.
I am working in proteomics and a sample of my data is
as follows
cluster-age clock-rate(evolutionary rate) scopclass
0.002 10 A
0.045 0.1 B
0.13
My understanding is that you want to replace each rate with its average
over the associated bin and then plot age against that. In that
case try this:
DF # test data
age rate bin
1 0.002 10.0 A
2 0.045 0.1 B
3 0.130 15.0 A
4 0.150 34.0 D
with(DF, plot(ave(rate, bin), age))
Or perhaps a bit simpler:
plot(age ~ ave(clock, bin), DF)
