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

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

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. With Open Office

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

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

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,

There was an inquiry on this list recently about plotting some simple error bars on a graph. Now Splus has a function (error.bar --- originally written by Sue Clancy of DMS, CSIRO, I believe) to do this job virtually at the touch of a key. (Well a few keys. :-) ) The error.bar function is written completely in raw S --- no calls to ``.Internal'' or anything like that. So it would be

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? --Mike C.

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?

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

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

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 that

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.

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

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!!! [Can't anybody ***read*** these days?] I asked: IS IT

Dear all, I am trying to conduct an enhanced version of factor analysis with a SPSS interface that allows to use R. This approach has been suggested in the recent article: Basto, M. and J.M. Pereira An SPSS R-Menu for Ordinal Factor Analysis. Journal of Statistical Software 46, pp. 1-29. My variables are ordinal-type and the tool of Basto allows to run polychoric correlations in the SPSS

Hello, helpeRs, I am attempting to reshape (either base R or package reshape) multiple .csv spreadsheets from a very unfortunate wide format to long format. ?Each spreadsheet looks something like this, after being read in to R: toy <- data.frame(year = rep(2007:2008,each = 20), month = rep(1:5,each = 4, length = 40), day = rep(1:2,each = 2,length = 40), hhmm = rep(1100:1101,length = 40),
