Can R handle graphic text ? I mean something like a pop-up message window or a text widget ? Thank you so much. -- Maura E.M

Hi, I noticed recently when installing the GDD package for R under GNU/Linux that it required the gd library (http://libgd.org/) for generating graphics. The resolution of this was to simply install the library on my system, and then GDD successfully installed without any complaints. However, the variant of GNU/Linux that I use is Gentoo, so I filed a bug requesting that a USE flag be set for

Hi, I'm trying to cast() some data, but keep on getting the following error... > norm.all.melted.height <- transform(all.melted.height, + norm.height = value / ave(value, SNP, Pool, FUN = max) + ) Warning messages: 1: In FUN(X[[147L]], ...) : no non-missing arguments to max; returning -Inf 2: In FUN(X[[147L]],

Hi all, I've just started using the Friedrich Leisch's Sweave package to generate LaTeX reports with results of my analyses embedded as required. I've encountered a bit of a problem though in the processing of the resulting *.tex file that is as far as I can tell, down to the fact that my variable names have underscores ('_') in their names. The relevant section of code

Hello to everyone! I have built CRAN task view for genetics. For now I have not submit it to CRAN yet and it can be accessible from: http://www.bfro.uni-lj.si/MR/ggorjan/software/R/Genetics.html http://www.bfro.uni-lj.si/MR/ggorjan/software/R/Genetics.ctv I have not submitted it to CRAN, since I would like first some opinion about it. Genetics is really so broad field that I belive one person

I am trying to get a measure of how R compares in usage as a statistical platform compared to other software. I would guess it is the most widely used among statisticians at least by virtue of it being open source. But is there any study to which I can refer? By asking this list I am not exactly adopting a rigorous approach! Best wishes John John Logsdon

Dear useRs, I'm trying to specify the colour of a factor with ggplot2. The example below gets me close to what I want, but it's missing a legend. Any ideas? Thanks, Thierry library(ggplot2) dataset <- data.frame(x = rnorm(40), y = runif(40), z = gl(4, 10, labels = LETTERS[1:4])) ggplot(data = dataset, aes(x = x, y = y, group = z)) + geom_point(colour = c("red",

Dear all, I'm not getting what I'm doing wrong. The line below from my read.fsa.bin function throws an error when just loading my AFLP package and disappears when I load the zoo package as well. #the line that throws the error Index <- which(Peak == rollmax(Peak, k = 1 + 2 * floor((min(diff(SizeStandard)) * Fs - 1) / 2), fill = -Inf)) #the error Error in UseMethod("rollmax")

Dear all, Can I do a permutation test if the number of individuals in one group is much bigger than in the other group? I searched the literature but I didin´t find any assumption that refers to this subject for permutation tests.

Dear all, I think I found a bug in utils::format.person when using style = "R" with a vector of comments. The comment section is not parsed properly. Please find below the mwe and the session info.

Dear all I would like to ask you if an assignment can be done inside a lapply statement. For example I would like to covert a double nested for loop for (i in c(1:dimx)){ for (j in c(1:dimy)){ Powermap[i,j] <- Pr(c(i,j),c(PRX,PRY),f) } } to something like that: ij<-expand.grid(i=seq(1:dimx),j=(1:dimy)) unlist(lapply(1:nrow(ij),function(rowId) { return

Thierry, thanks for this, this is a bug in utils:::.format_person_as_R_code(). This calls deparse() on the elements of the person object with the default width.cutoff = 60. As your comment exceeds this width, the erroneous formatting is produced. The simplest reproducible example I could come up with was: p <- person(".", comment = c(foo = ".....................",

Hello, is it possible to create two uncorrelated random vectors for a given distribution. In fact, I would like to have something like the function "rnorm" or "rlogis" with the extra property that they are uncorrelated. Thanks for your help, Luba [[alternative HTML version deleted]]

If you tell me how to update R itself automatically, I will go for your advice. I am not aware of any method to do it... Bye Rick "ONKELINX, Thierry"

Dear all, I'm trying to use a Markdown vignette with UTF-8 encoding. It compiles well when knitting the vignette in RStudio, but it fails to recognize the UTF-8 settings when building the source package. Can someone point out what I'm doing wrong? I tried to put the relevant information below. Best regards, Thierry Details: Using 64-bit R 3.1.2 with encoding = "native.enc"

Hi, I have a R script file with Persian letters in it defined as a variable: #' @export letters_fa <- c('???','?','?','?','?','?','?','?','?','?','?','?') I have specified the encoding field in my DESCRIPTION file of my package. ... Encoding: UTF-8 ... I also included

Hi All, I am running an Rscript with a bunch of algorithms that are UNSTABLE under some parameter settings. At a certain point one of them sends error massage and my whole run STOPS! What I would like is to save the error massage in some file or variable and carry on to the next command line without stopping this run... Any help or ideas would be welcome, please, with a concrete example (not

Dear all, When one tries to load a non-installed package you get the error: Error in library(xyz) : there is no package called 'xyz' I noticed on several occasions that this puzzles beginners. Therefore I suggest to change the error description in: Error in library(xyz) : there is no package called 'xyz' installed on this machine. Check the name of the package or use

Dear all, When running R CMD check on our package, we get an error on the examples. Error in grDevices::dev.off() : cannot shut down device 1 (the null device) None of the examples in our package generates plots. grDevices::dev.off() is code added by R CMD check. A workaround is to have at least one example which has some plot. Is there a better solution? We are using R 3.5.1 Best
