Hi I want to install some versions of R simultaneously from source on a computer (running Linux). Some programs have an option to specify a suffix for the executable (eg R would become R-2.7.2 when the suffix is specified as "-2.7.2"). I did not find this option for R - did I overlook it? If it is not, how is it possible to have several versions of R on one computer, or is the only way

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 asked about if there is any way of opening URLs from the help browser in the same window of the same dillo browser - here is the answer.

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 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

I need the combination of two character vectors, i.e: x <- c("a", "b") y <- c("x", "y") z <- THEFUNCTION(x, y) z == c("ax", "ay", "bx", "by") I promise I will

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 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 is it possible to specify the shape of the point to be used in ggplot (as with pch in plot)? I couldn't find anything in the help. Thanks Rainer -- Rainer M. Krug, Dipl. Phys.

Hi I heard so much about Emacs and ESS that I decided to try it out - but I am stuck at the beginning. Is there anywhere a beginners manual for Emacs & ESS to be used with R? even M-x S tells me it can't start S-Plus - obviously - but I want it to start R... Any help welcome (otherwise I will be stuck with Eclipse and R) Rainer -- Rainer M. Krug, Dipl. Phys. (Germany), MSc

Hi I have the following loop and would like to vectorize it. Any ideas if it is possible? Thanks, Rainer Tha Loop: for (i in 2:Result$NoSims) { ppp <- runifpoint(Result$NoPlants) K <- Kest(ppp) Result$LSim[i,] <- sqrt(K$iso / pi) - K$r CM <- (Result$LSim[i,] * Result$LSim[i,]) / abs(K$r[2] - K$r[1]) Result$SigCM[i] <- sum(CM, na.rm=TRUE) print(i) flush.console() }

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 use the following code and it stores the results of density() in the list dr: dens <- function(run) { density( positions$X[positions$run==run], bw=3, cut=-2 ) } dr <- lapply(1:5, dens) but the results are stored in dr[[i]] and not dr[i], i.e. plot(dr[[1]]) works, but plot([1]) doesn't. Is there any way that I can store them in dr[i]? Thanks a lot, Rainer -- Rainer M. Krug,

Hi I have (8 measures * 96 groups) = 768 datasets for which I did linear regressions using lm(). Now I want to compare the slopes for each of the 8 measures in each of the 96 groups. As I understand , I can not use > anova(lm1, ..., lm8) as the lm1 ... lm8 are based on different datasets. I also read in previous discussions in this list, that I can see if the slope +- stddev(slope)

Hi I have problems installing R 2.1.1. from rpm (R-base-2.2.0-1.i586.rpm) on SuSE 10.

Hi I am using R 2.2.1 under Linux (SuSE 10) and would like to know if it is possible to create graphs, i.e. jpeg(filename=fn) try( coplot( mor$I_Morisita ~ mor$Year | mor$RunStr, show.given=FALSE) ) dev.off() from a text console? It gives me an error message on the jpeg() command: Error in X11(..snip..) unable to start device jpeg In addition: warning message: unable to open connection to
