Hello, I would like to run some code in parallel with each cluster reading/writing to a different working directory. I've tried the following code without success. The error I get is: "Error in setwd(x) : cannot change working directory" library(parallel) dirs <- list("out1","out2","out3") # these directories are located within the current

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I restored a filesystem by using rsync to copy directories and files from a backup volume to the newly recreated volume. All of the re-created files were given the current date and time rather than the original file's timestamp. I am sure there was a way to prevent that from happening. Is there a way to use rsync to set the timestamps

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 want to use order() to get the order of a vector. But I would need a different behavior when ties occur: similar to the parameter ties.method = "random" in the rank() function, I would need to randomise the ties. Is this possible? Example: x <- rep(1:10, 2) order(x) [1] 1 11 2 12 3 13 4 14 5 15 6 16 7 17 8 18 9 19 10 20 order(x) [1] 1 11 2 12 3 13 4 14 5 15

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 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 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 while teaching R, the question came up if it would be possible to add a picture (saved on the HDD) to a graph (generated by plot()), which we could not answer. It might easily kill a clean graph, but: is there a way of doing this, even one should not do it? On a similar line of thought: is it possibe to define own symbols so that they can be used in the plot function with pch=? Rainer

Hi I have a plist t which contains size measurements of individual plants, identified by the field "plate". It contains, among other, a field "year" indicating the year in which the individual was measured and the "height". The number of measurements range from 1 to 4 measurements in different years. My problem is that I would need the LAST measurement. I only

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 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 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 Consider the following code > x <- rep(1:13, 13) > y <- 1:3 I want to select all elements in x which are equal to 1, 2 or 3. I know that I could use > sel <- x==y[1] | x==y[2] | x==y[3] > x[sel] to obtain the values, but in my analysis, the y-vector is thousands of elements long. Is there any way, that I can do that easily? Thanks Rainer -- Rainer M. Krug, Dipl.

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

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,
