Display an Image on a Plane
Hi, I am new to R and I would like to display an image on a plane in a 3D plot, i.e. I would like to be able to specify a theta and a phi parameters like in the function persp to display a 2D image on an inclined plane. Regards, vincent [[alternative HTML version deleted]]

A question about R environment
Hi all, I created environment "mytoolbox" by : mytoolbox <- new.env(parent=baseenv()) Is there anyway I put it in the search path ? If you need some background : In a project, I often write some small functions, and load them into my workspace directly, so when I list the objects with ls(), it looks pretty messy. So I am wondering if it is possible to creat an

Suitability of R for Algorithm simulations
Greetings, Sorry for the basic question, but I am trying to find out if R is a suitable platform for what I want to do... I am interested in creating simulations of distributed algorithms (i.e. team formation, Byzantine Generals , P2P communication modeling, mobile networks) that would be represented in GUIs. I would like to be able to instantiate an object for each node in my simulated

xy.coords(MATRIX) bug in code or documentation (PR#8937)
Hi, people. xy.coords() does not behave like its documentation says, when given some matrices. ?xy.coords says: If 'y' is 'NULL' and 'x' is a [...] formula [...] list [...] time series [...] matrix with two columns [...] In any other case, the 'x' argument is coerced to a vector and returned as *y* component [...] Now, consider this short

R-generated animation of a polynomiograph
Hi, people. Two days ago, I sent to this list a little toy for exploring polynomiographs (yet, the mathematical formulas were not polynomials anymore, so the name is not really appropriate). After studying R calls, expressions and functions a bit more, I gave myself the homework of producing an animation out of my recent toy. The resulting animation, and also the sources, are available at:

Excel (off-topic, sort of)
Except for the ability to perform circular recalculation, I believe that the closest programming analogy to a spreadsheet is a functional programming language. Check out Haskell (or LISP or Erlang) to do what you describe. -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of Fran?ois Pinard Sent: Wednesday, August 29, 2007

Truncated labels in hist (PR#8864)
Hi, people. Executing the following command: hist(rpois(100,5), labels=TRUE) yields a graphic in which some labels are truncated (on an X11 device). The truncated labels are those over the highest bars. The hist function should ideally manage enough room for the labels, automatically. (Specifying ylim solves my problem, but yet, hist could be frienlier.) --please do not edit the

Combine matrix
Hi R user, I am new to R, and I have a very simple question for you. I have two matrix A and B, with internally redundant rownames (but variables are different). Some, but not all the rownames are shared among the two matrix. I want to create a greater matrix that combines the previuos two, and has all the possible combinations of matching rownames lines among matrix A and B. looking for the

R 2.5.1 - Rscript through tee
Hi, people. I met a little problem for which someone might have a solution. Let's say I have an executable file (named "pp.R") with this contents: #!/usr/bin/Rscript options(echo=TRUE) a <- 1 Sys.sleep(3) a <- 2 If I execute "./pp.R" at the shell prompt, the output shows the timely progress of the script as expected. If I use "./pp.R | tee

Matrices given to pt? [was: [R] for loops and counters]
Hi, people. I was a bit intrigued by the message quoted below. Indeed, if pt() is given a matrix, it returns a matrix. Should this feature be documented? ?pt speaks about "a vector of quantiles", and says nothing about the type of what it returns. The same might presumably apply to other distribution-related functions. ----- Forwarded message from Martyn Plummer <plummer at

HOW to Create Movies with R with repeated plot()?
Dear R-helpers, Is it possible to create a type of 'movie' in R based on the output of several figures (e.g., jpegs) via the plot() function. I obtained dynamic results with the plotting function and would like to save these as a movie (e.g., avi or other formats)?

Re-binning histogram data
Hi, Short Version: Is there a function to re-bin a histogram to new, broader bins? Long version: I'm trying to create a histogram, however my input-data is itself in the form of a fine-grained histogram, i.e. numbers of counts in regular one-second bins. I want to produce a histogram of, say, 10-minute bins (though possibly irregular bins also). I suppose I could re-create a data set as

Mere chat on vectorisation matters
Hi, people. Allow me to chat a tiny bit on two vectorisation-related matters, in the context of R. I'm curious about if the following ideas have ever been considered, and rejected already. First is about using the so-called Duff's device for partially unrolling loops. I did not overly check in R sources, and am not familiar with them anyway, but the only usage I saw is within

Difficulty with qqline in logarithmic context
Hi, R friends. I had some difficulty with the following code: qqnorm(freq, log='y') qqline(freq) as the line drawn was seemingly random. The exact data I used appears below. After wandering a bit within the source code for "abline", I figured out I should rather write: qqnorm(freq, log='y') par(ylog=FALSE) qqline(log10(freq)) par(ylog=TRUE)
