Hi all! I read R Extensions manual. But still I am not sure how to call R functions from C. Would any of you give me a sample C code to show how to call R functions - for instance, time series functions - from C in the embedded way of C code? [[alternative HTML version deleted]]

Hi I know how to referenc R in a scientific paper - but is there a standardised way to reference packages?

I'm having a very hard time making R CMD check produce a clean check on examples because of the timings inserted into examples by R CMD check. I am getting a difference on every example output caused by timing information being inserted by 'R CMD check'. The current 'Writing R Extensions' manual[1] states on p. 14: If directory tests has a subdirectory Examples

Hi I am sure this is simple - but how can I convert one charecter vector into one string? example: x <- c("This ", "is ", "one ", "sentence.") should become "This is one entence" Thanks Rainer -- NEW EMAIL ADDRESS AND ADDRESS: Rainer.Krug at uct.ac.za RKrug at sun.ac.za WILL BE DISCONTINUED END OF MARCH Rainer M.

Hi I am using mathematical anotation to make the labels in a barplot in italics. as an example (adapted from http://finzi.psych.upenn.edu/R/Rhelp02a/archive/129808.html): tt <- c("italic(First~~set)", "italic(Second~~set)", "italic(third~~set") barplot(1:3, names.arg=parse(text=tt)) But I would like to have it with "set" in a second column, like tt

Hi I am trying to install the package "pheno", but it needs the package "nprq" by Roger Koenker et al. which I can I find this package? It does not seem to be on CRAN and googling also doesn't give me an URL - is it still somewhere available?

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.

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 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 I have use dovecot together with offlineimap to download my gmail account on a single user computer and I have only one maildir (~/Maildir). As I switched to Mac, I would like to use spotlight to index my mails, which apparently does not work as they are in hidden directories (.directories). So I would like to change to LAYOUT=fs. Is there an easy way to migrate my email structure? I have

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,

?tempdir says By default, ?tmpdir? will be the directory given by ?tempdir()?. This will be a subdirectory of the temporary directory found by the following rule. The environment variables ?TMPDIR?, ?TMP? and ?TEMP? are checked in turn and the first found which points to a writable directory is used: if none succeeds ?/tmp? is used. Unfortunately, it doesn't seem to

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?

-----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... 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

Hi I want to do a series of linear models, and would like to define the input arguments for lm() as variables. I managed easily to define the formula arguments in a variable, but I also would like to have the "subset" in a variable. My reasoning is, that I have the subset in the results object. So I wiould like to add a line like: subs <- dead==FALSE & recTreat==FALSE which

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Just to be sure: I couldn't find a way of creating an interactive 3d graph which can be embedded in a pdf - is it correct that this can not be done with R?

Hi I am comparing four different linear mixed effect models, derived from updating the original one. To compare these, I want to use anova(). I therefore do the following (not reproducible - just to illustration purpose!): dat <- loadSPECIES(SPECIES) subs <- expression(dead==FALSE & recTreat==FALSE) feff <- noBefore~pHarv*year # fixed effect in the model reff <-

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
