Hi I know this only affects a small number of subscribers, so I apologize to the "Non Stellenbosch University subscribers" for the noise. Two weeks ago, four R users met and discussed the possibility of forming an interest group of R users at SUN. The interest group (R at SUN) has the aim of: ? Promote the use of R at SUN (Stellenbosch University); ? Organize Hons stats courses using

Hi is there an easy and fast way, to generate a BibTeX file of all installed / loaded packages and R? I know about toBibtex(citation()) to extract the BibTeX for a single package, but how can I generate a file containg citations for all installed / loaded packages?

Hi I upgraded to R 2.10.0, and I encounter a problem with some packages on R, installed via apt-get.. They are still compiled by 2.9 and give me an warning when I load the packages. Will these packages be recompiled with R 2.10, or should I rather switch to self-compiling? Cheers, Rainer -- Rainer M. Krug, PhD (Conservation Ecology, SUN), MSc (Conservation Biology, UCT), Dipl.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I have to replace the last element of a vector with 0, but the length of x is not known at coding time. So I do the following: x <- 1:10 x x[length(x)] <- 0 x it is working nicely, but I am wondering: is there a more elegant solution( like tail(x, 1) <- 0 , which does not work)?

Hi Let's assume, I have a dataset of 1000 datapoints, which represent daily recordings of a measurement. They are stored as a ts object (see example below) Now I want to represent them as a barplot. I found the barplot in the zoo package, but I have one problem: the x-axis labels. I would like to have the x-axis labels as either years only (located at the beginning of the year), or

Hi I know this is likely documented somewhere, but I can?t find it. How can I install R > 4.0.0 on Debian 9 Stretch? Thanks a lot, Rainer -- Rainer M.

Hi I am using Ubuntu Hardy, and I installing many packages from source. I am keeping my R packages fairly up to date. My question is: is there a way, of keeping the source packages, so that when I am installing a new version of R, an update.packages(checkBuilt=TRUE) will only fetch the packages when newer ones are available, but otherwise will use the local copies? To rephrase it, is it

Hi this might be a little bit off topic, but here it goes: lets assume I have the following: set.seed(13) dat1 <- rnorm(2000, mean=10, sd=10) dat2 <- rnorm(100, mean=10, sd=20) d.all <- density(dat, n=1024) d.co <- density(x[[v]], , from=min(d.all$x), to=max(d.all$x), n=1024) d.diff <- list( x = d.all$x,

Hi I am testing a package, and after I make changes, I have to close R and open R again to load the new version (same version number) of the package I am working on. So my question: is there a function which removes a package, i.e library(myPackage) > Package is loaded unlibrary(myPackage) > package is not loaded any more Thanks, Rainer -- Rainer M.

Hi Dirk, Thanks for the explamnayion - Debian is running in a VM (and nothing really installed on it) , and I think the easiest is for me just to install Debian 10 and to use that one.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I would like to create a Namespace during runtime, and not during loading a package. My reasoning is that I want to be able to store a number of variables and to "protect them from the user" (might be even myself). The code will not be in a package, but will be source()ed. Next step: pass variables from org mode / emacs to R and to

Hi I want to use R's recycling rule. At the moment I am using the following: x <- c(1, 2, 3) n <- 10 ## so using the recycling rules, I would like to get from FUN(x, n)==1 ## I am doing: xRecycled <- rep(x, length.out=n)[n] This works, but it seems to me that I am missing something really basic here - is there more straightforward way of doing this?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I know there is a function - I have used it before - but I always forget what it is called...

Hi is there an alternative to par(new), for ading data to a plot for a different y-axis? My problem with par(new=TRUE) is, that it re-defines all axis and labels (as in example 1) and one has to use xlim=... to fix the x-axis. I am looking for something, which simply resets the y-axis, so that a new plot() (or points()/lines()) keeps the x-axis, but re-defines the y-axis. Is there something

Hi This is OT, but I need it for my simulation in R. I have a special case for sampling with replacement: instead of sampling once and replacing it immediately, I sample n times, and then replace all n items. So: N entities x samples with replacement each sample consists of n sub-samples WITHOUT replacement, which are all replaced before the next sample is drawn My question is: which
