exact inference tests
R-community--
Is there a contributed package (or does anyone have code otherwise) for
exact inference tests and resampling statistics ala' StatExact? I've
perused the package descriptions on CRAN and didn't see anything, but
since several contain many functions, I thought perhaps I'd ask.

rarefaction variance
Here's a question for ecologists on the r-help list-- I'm addressing this
to ecologists in particular because they're most likely to be familiar
with the equation in question but I'll be happy to discuss the problem
with anyone who's willing to take a whack at it.
I'm trying to write a function to calculate the large sample variance of
species richness estimates by

Kate problem
Hello,
I have just installed R 1.5.1 on a new SuSE 8.0 install using the
binaries on the home page. I am trying to configure the KDE editor Kate
to use from R. R seems able to launch it fine, but it crashes when I
try to save the file I am editing.
Is there a fix?
Thanks,
John.

pattern on bars?
Colors are real nice, but the publication I'm preparing these barplots for
permits only black and white. The Splus plot options ``dbangle'' (or plain
``angle'') and ``density'' (as on p. 65 of MASS 1st ed.) don't seem to be
available in R. Is there another way to do this?
I'm running R 1.1.0 on Linux (intel). Thanks.

cluster analyses
I'm clustering rather large data sets and would like to cut the dendrograms
to get a better view of specific components. I calculate the dissimilarity
matrix using daisy() because I have a mixture of variable types: factors,
ordered factors and numerical variables. If I want one dendrogram, I use
agnes() for the agglomerative nesting and pltree() to draw the dendrogram.
That way, I get the

Legality of copying from Splus.
A few days ago, I sent a question to the r-help list enquiring
about the
*** LEGALITY ***
of porting a function from Splus into R. As a particular example,
I referred to error.bar.
Several people posted code for various versions of error.bar which
they had written, but that was NOT WHAT I WAS ASKING FOR/ABOUT!!!

zero replacement
AARRGGHH! Sometimes it's the simple things that are particularly frustrating,
especially late at night....
Can anyone suggest a simple means for replacing all of the zero values in a
matrix with NANs? I ended up writing an awk script to massage the input file,
which works, of course, but is rather an inelegant blunt instrument. I'd
prefer an R operation. I'm certain that

hatch or line fill
M. Camanm posted in Jul 1999 the following message:
"
Is there any way to fill the bars in a barplot() with solid lines for
postscript output, i.e. cross hatch or parallel
lines, or a halftone gray rather than (semi) continuous-tone gray
produced by gray()? S allows this, or at least
used to, via the angle and density arguments to barplot(). The objective
of course, is to produce camera

State space modelling
Hi, I'm new to R and am trying to implement a state-space model, and do some
simulations looking at how well it works. Does anyone have an example I
could use as a template? I'm having trouble working out where to start, and
haven't been able to find anything similar in the help files or on the web.
My example is a surplus production fisheries model, so something similar to

DCom / StatConnector / Windows-Cygnus-Gcc ?
Hello List !
I want to use R as statistical & Graphical Tool for biological
simulation programs. So, I want to combine my programs (written
under cygnus-gcc on NT4.0) with R 1.0.1.1 under Windows.
The data, produced by my program will be sent to R. There it should
be statistically "transformed" and graphically displayed. The
simulation program may wait until R has calculated

rw-patched destiny
R-devel team--
Will the patches that Brian Ripley has posted be rolled into the main
R-win distribution on CRAN? I ask because I'm going to be using R in one
of my ecology courses during fall semester, and although I'll probably
give the students a CD with R and a variety of other tools bundled onto
it, I'll also tell them where to upgrade and look for additional
packages and other

various ordinations
Colleagues,
I'm developing a library of functions for community ecology analyses and
have a couple of questions that I've not been able to answer via faqs or
docs.
1) Are there existing functions for:
a) Bray-Curtis (polar) ordination?
b) non-metric multidimensional scaling (NMDS)?
c) canonical correlation analyses (CCA and DCA)?
d) TWINSPAN (doubtful...)?
2) If not,

R 1.5.0 printing problems on Win98?
Colleagues--
I'm having a problem upgrading to R 1.5.0 on a Windows 98 computer. The
windows() graphics device seems to behave strangely. A call to windows()
opens an active graphics device, as does a call to a plotting function,
e.e. plot(1:5,1:5). So far so good. When I click on the Printer icon
(with the graphics device active) nothing happens. Likewise when I use
win.print() from the

[R] Free Software Application for UNIX/Linux and Microsoft Windows
Dear Michael Camann,
My concern was after having a hetero-computing environment for many years, I
found that I had to keep an old version of Microsoft Windows based
applications to be able to interact with my constituents. This at times can
become very expensive. I have had to limit my budget on the UNIX/Linux
platform to compensate for Microsoft Windows based applications.

identify() output doesn't print
Hope this isn't a faq, but....
I'm using R 0.99 for Windows under Win98. When I label points in a scatterplot
with identify(), the labels appear as expected on the graphics device, but do
not print when I select the printer icon. The scatter plot itself prints just
fine-- only the output from identfy() is missing. Can anyone offer any hints?

To make a graph for 4 functions
lets say I have these function and I want to have a graph on them
y0=x^2
y1=x^3
Then I say this
x=seq(0,10,length.out=100)
plot(x,y0,y1,type="l")
but R does not give me a graph. How would you do it?

Count the number of consecutive 1's
Hi All,
We have a raw dataset that, on the sampling time column, for example:
t <- c(0,1,2,5,0,5,0,2,5)
And we need to create a second column that indicates the day of the sampling, so the end result of what we want is a vector:
1,1,1,1,2,2,3,3,3
Additional information that might simplify the matter is that, for each day, the time starts with zero and ends with 5.
I am a beginner with R.? So

Integration in R
Dear R-users,
I am facing problem with integrating in R a likelihood function which is a
function of four parameters. It's giving me the result at the end but
taking more than half an hour to run. I'm wondering is there any other
efficient way deal with. The following is my code. I am ready to provide
any other description of my function if you need to move forward.

Request - adding recycled "lwd" parameter to polygon
Hello dear members of R-help and R-core mailing list,
I am not sure if this request is a "ticket" that should be filled somewhere
outside the mailing list. If so, I apologize for not doing and would like
to know where I should have filled it.
And to the subject matter:
I would like to use a command like this:
