Hi, R people. I'm shy reporting this, as a bug in this area sounds very unlikely. Did I make my tests wrongly? I'm still flaky at all this. Let me dare nevertheless, who knows, just in case... Please don't kill me! :-) Not so long ago, I wrote to this list: > (For now, [the library code] works only for me when I do _not_ use `-l > MY/OWN/LIBDIR' at `R CMD INSTALL'

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:

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

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

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

Hi, people. A tiny suggestion for the system.time function. Could the returned vector have names? These could be like: c("User", "System", "Elapsed", "Sub.User", "Sub.System") That would then produce self-documenting output. -- Fran?ois Pinard http://pinard.progiciels-bpi.ca

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

Wandering in R archives, and seeing the message attached below, I noticed that: mapply(rep,times=1:4, MoreArgs=42) still segfaults on R 2.2.0, and thought I should be a good citizen and report it, even if I do not have an actual problem

Hi, people! This is my first babble on this list, please be kind! :-) Last Tuesday, I wrote to the (likely) Webmaster of the R site to report a little problem, but also to ask for advice about how to get a bulk copy of the mailing list archives, from 2002 to now. While I quite understand that from Tuesday to now, there has been little time, and it is only normal that I did not receive a reply

Good working knowledge of a DBMS is almost invaluable when it comes to working with very large data sets. In addition, learning SQL is piece of cake compared to learning R. On top of that, knowledge of another (SQL)

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

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)

Hi, R people. In ?factor, in the "Examples:" section, we see: ## suppose you want "NA" as a level, and to allowing missing values. (x <- factor(c(1, 2, "NA"), exclude = "")) is.na(x)[2] <- TRUE x # [1] 1 <NA> NA, <NA> used because NA is a level. is.na(x) # [1] FALSE TRUE FALSE I'm a bit confused by this example, as I

Hi, people. This is about R 2.3.0 under Linux. It seems that edit() may change a function environment.

How can I parse a YAML file in R 2.6.0 in Windows? I cannot get the RYaml package to compile in Windows, I can't find a MinGW compiled .dll for an existing YAML parser like syck (which would appear to be the best hope for creating my own R wrapper functions), and I don't know how to call a Ruby or Python function from R (so that I could parse the file in Ruby or Python and pass the parsed

Can someone hit me with the appropriate clue-by-4? is there an available package for CentOS5 which provides the metafont command, or a replacement? What is the name and which repo? please. I have a font bundle I need to use (which is not provided in an RPM that I can find), but metafont does not seem to be available. tetex provides the /usr/share/texmf/metafont directory structure, but not a

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]]
