similar to: Keeping package sources for recompilation with new R version?

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.

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 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 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? Cheers, Rainer -- NEW

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

Hi I want to change a control parameter for an nls () as I am getting an error message "step factor 0.000488281 reduced below 'minFactor' of 0.000976562". Despite all tries, it seems that the control parameter of the nls, does not seem to get handed down to the function itself, or the error message is using a different one. Below system info and an example highlighting the
