Good day, Could the documentation of graphics devices give some explanation of how big the bitmap limits are? For example, > png("Figure1A.png", h = 7, w = 7, res = 1000, units = "cm") Results in Error: unable to start png() device, but the help page of devices doesn't explain that there are any limits or how they are determined. The wording of the error message could

Good day, I believe from the documentation that folders in R_LIBS should appear in the output of .libPaths, but they do not. The documentation contains "The library search path is initialized at startup from the environment variable R_LIBS ..." However, $ export R_LIBS=/users/stgrad/dario/tmp/ $ Rscript -e ".libPaths()" [1] "/dskh/nobackup/biostat/Bioconductor"

Good day, It is implemented by the CRAN package multicon. The function is named popsd. But it does seem like something R should provide without creating a package dependency. -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia

Hello, capture.output produces a different result if the S4 object was created with a constructor than if the body of the constructor is copied and pasted. setClass("TransformParams", representation( transform = "function", otherParams = "list") ) setGeneric("TransformParams", function(transform, ...) {standardGeneric("TransformParams")})

I have a simple function : f <- function() { if(requireNamespace("ggplot2")) qplot(Sepal.Length, Petal.Length, data = iris, color = Species) else message("No graphics, just text.") } ggplot2 is in the Suggests field of the DESCRIPTION file. When I load the package, and run the function, I get an error : > f() Loading required namespace: ggplot2 Error in f()

Hello, I am writing an interface to some functions from the CRAN package pamr, which is poorly written. I have a S4 method I declared with setMethod. I'd like to provide a signature of "pamrtrained" which is the class of object that training creates. The last two lines of code of pamr.train are : class(junk) = "pamrtrained" junk How can I dispatch on these kinds

Hello, I have a minimal example that shows a problem I'm having with parallel processing. library(parallel) mcmapply(function(x, y) { print("Running") Sys.sleep(10) }, as.list(1:10), as.list(10:1), mc.cores = 16, SIMPLIFY = FALSE) I see "Running" printed once every ten seconds. I read the documentation for mcmapply, but I don't understand why it wouldn't

Good day, I'd like to suggest the addition of an as.list method for a by object that actually returns a list of class "list". This would make it safer to do type-checking, because is.list also returns TRUE for a data.frame variable and using class(result) == "list" is an alternative that only returns TRUE for lists. It's also confusing initially that > class(x) [1]

Hello, The e1071 function naiveBayes gives an error when called by do.call, although it doesn't give any error if I call it manually. Browse[1]> trainParams at classifier function (x, ...)

Good day, The server administrator recently upgraded the operating system from Debian version 7 to version 8 and R from version 3.1.2 to version 3.2.2. The default font used in plots has changed and I've asked him to restore the previous font. What instructions should I tell him about restoring the font ? -------------------------------------- Dario Strbenac PhD Student University of Sydney

The documentation states that "save.image() is just a short-cut for save(list = ls(all = TRUE), file = ".RData")". However, if I do Browse[1]> ls(all=TRUE) [1] "expression" "orderedFeatures" "predictParams" [4] "resubstituteParams" "trainParams" "verbose" Browse[1]>

Good day, The capabilities function gives a logical result of which features R has been compiled with. Is there a more advanced variety of the function that will give the version number of the library, or its system path, rather than simply TRUE ? -------------------------------------- Dario Strbenac PhD Student University of Sydney Camperdown NSW 2050 Australia
