Hello R-List, ** This e-mail was initially bounced. Please forgive any duplicates.** I'm creating a new generic function and 3 associated methods, in which each of the methods only needs a subset of the arguments specified in the generic. So, I create the generic like so (with the signature defaulting to all of the args) ... setGeneric( name="myFunction", def =

Hi All, I'm still actively researching this problem (reading R-ext manual), but I hoped that I might be able to get some additional insight from the list given that I'm fairly new at writing R extension code. Problem: I have some fairly simple code (.Call interface) that makes a call to another shared library, which, in turn, calls routines in an HDF5 shared library. The good news

Hello R-List I've run into a minor problem with ggplot2. In particular, I get an error message when trying to plot a horizonal line through zero. Here is what I do: plt.df <- subset(xfm.df, select=c(stage, subj, tX)) plt <- ggplot(pp.df, aes(x=stage, y=tX, group=subj)) + geom_line() plt plt <- plt + geom_hline(intercept=0) plt The first plot yields a most lovely graph.

Hi all, I've finally started to use Rscript for my statistical scripting needs, and find I'm being blocked by what must be a very simple problem. Specifically, the command lines for my scripts usually contain: (1) the script name, (2) one or more options and their arguments, and finally, (3) one or more filenames to be processed. While the "getopt" package seems to provide

Hi all, I have been having problems generating png files on a Mac running OS X 10.6.8. Here's a simple example > png("foo.png", type = "cairo"); plot(1:10); dev.off(); null device 1 libpng warning: Application built with libpng-1.2.26 but running with 1.5.2 The resultant file is of size 0 Kb. Is this the proper place to report this issue? Or should

(moved from R-help) I tried this on Ubuntu with R-2.14.1 built from source, and I do not get the segfault problem. (I don't at the moment have a debian binary R, or I would confirm whether I get the segfault problem.) My sessioninfo() is reporting additional information about namespace imports: > library(ggplot2) Loading required package: reshape Loading required package: plyr

Dear list, I have a reference class which should act as a "generic" superclass for other classes. I've read the respective section at ?setRefClass and put the name of the superclass to the 'contains' argument of an example subclass (see class defs below). Classnames are set in a way that shouldn't result in collation issues (virtual def sourced before superclass def

Hello, I wrote a class like so: > rcfdpsuperclass <- setRefClass( > Class="rcfdpsuperclass", > fields = list( > RcfpdVersion = "character"), > methods = list( > initialize = function(){ > 'Populates fields with defaults and lock as appropriate' > initFields( > RcfpdVersion =

For Whom the Gaza Bell Tolls -- Part 1 By Edmund Connelly for The Occidental Observer January 16, 2008 ?The Israelis can kill whomever they want whenever they want.? --Paul Craig Roberts I sometimes think that it?s pointless for Americans to talk much about recent events in Gaza because we know how it will play out ? America will do absolutely nothing to interfere with the ongoing massacre.

This bug appears intermittently in R CMD check when reference classes have finalize methods. The problem is that garbage collection can be run after the methods package is no longer available. It affects (periodically) the Bioconductor AnnotationDbi package as well as packages that contain Rcpp classes. To reproduce: library(methods) a = setRefClass("A",

Hello, I am somewhat new to R programming and a novice C++ programmer. I'd like to know if I should use setRefClass() to manage objects, functions, and data in a very large program I am attempting to code. See: http://stat.ethz.ch/R-manual/R-devel/library/methods/html/refClass.html I like the referential class structure that C++ provides and R seems to provides via setRefClass(). Mainly

I am trying to determine how to customize the date and time display of system utilities and user programs using the locale settings. What I really want is some sort of utility program that does the same thing for CentOS as the Regions Settings Control Panel app. for MicroSoft Windows accomplishes, but I have no hope of seeing that. I have traced the login locale processing through /etc/profile

Dear list, I was wondering if you could help me out in clarifying something: Is it possible to use class "ANY" in slots/fields of formal classes if you a) do not want to restrict valid classes of that field and b) if you are making explicit use of class inheritance? It seems to work in simple scenarios but produces errors when class inheritance comes into play. So I was

Hi, I have a script I can run step by step through the R interpreter and it works fine. I then run as a shell script with Rscript and it fails. The error message comes when I am creating a model matrix with model.matrix.default(). Error in `contrasts<-`(`*tmp*`, value = "contr.Treatment") : could not find function "is" Calls: model.matrix.default ->

I am trying, without success, to compile a custom locale for the utf-8 character set. I have issued this command: localedef --no-archive -f UTF-8 -i /usr/share/i18n/locales/en_CA at yyyy-mmm-dd en_CA at yyyy-mmm-dd.utf8 which produces the requisite files without reporting an error but which none-the-less insists on using the iso-8859-1 charset: LC_ALL=en_CA at yyyy-mm-dd locale charmap

Dear John and others, I've been wondering about whether there's any way to indicate a "nil" reference class object, which will represent "no value", and be tested for, but not fail the internal type checking. NULL is the obvious choice (or seems so to me), but can only be used if an explicit class union is created: > Foo <- setRefClass("Foo") > Bar

Dears, I have a question about copying reference objects using the initialize method. 1) If the latter has no arguments, there is no problem to copy an object. myClass = setRefClass("myClass", fields = list(value = "numeric") ) myClass$methods(initialize = function(...){ ? value <<- 1 ? callSuper(...) }) newObject = myClass$new() newObject$value = 2 copyObject =

Hi, I've begun to use the lme4 package, rather than nlme, for more flexibility during modelling, and running the examples in lmer I receive this error message: ---<---------------cut here---------------start-------------->--- R> (fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)) Error in printMer(object) : no slot of name "status" for this object of class
