similar to: what is the preferred method to create a package local variable?

I feel tedious when I define a S4 class and the methods. For each method, I have to call both setMethod and setGeneric (or both setReplaceMethod and setGeneric). I would like a more compact grammar so that I can reduce the key strokes. I'm wondering if there is a better way available. setClass( Class='A', representation=representation( x='numeric' )

Hi R version 2.4.0 alpha (2006-09-06 r39158) MacOSX 10.4.7 There was a thread some time ago as to whether the structure created by package.skeleton() would pass R CMD check. I have an example where package.skeleton() gives an R file that gives an error when sourced. If I type setClass("brob", representation = representation

Hello, I need to retrieve datas from bloomberg. I want to retrieve those datas in the fastest way as possible. I have two options: writing the datas from bbg to excel and reading from r the excel sheet or directly read the datas from from r with a Rbbg connection. Which connection is faster?

Hi I have the code like I show below. The problem here is that I have a setReplacementMethod to set the value of my class slot. However, this function doesn't work when I call it within another function definition (declared by setMethod) of the same class. I do not understand this behavior that much. I'm wondering how to make this work? Any help would be really appreciated. Thank you.

Hi, Can anyone give me a pointer on howto make a package execute a function at loading? Following an older post (http://bit.ly/cS1Go4), I'd like to do something along the lines of > .localstuff <- new.env() > .localstuff$OftenUsedData <- read.csv(...) upon loading the package ... Thanks, Joh

If someone is able, can you tell me if there is a better way to do this? More specifically, do I have to rewrite all of the data members stuff and extend stuff of parent class in the child class? See below. Thanks in advance! Example 1: setConstructorS3("ClassA", function(A,x) { if(missing(A))A=15; if(missing(x))x=NA; extend(Object(), "ClassA", .size = A, .x=x

Dear R-users, i encountered some problems when trying to adjust the line width of the axes and stripes in a plot created with ggplot2. I use the "barley" dataset of the lattice package to illustrate my problem: library(ggplot2) library(lattice) barley[["SD"]] <- 5 limits <- aes(ymax=barley$yield + barley$SD,ymin=barley$yield - barley$SD) p1 <-

Folks, I want to automate some graphing using ggplot. Here is my code graphChargeOffs2<-function(coffs) { ggplot(coffs, aes(levels)) dataNames<-names(coffs)[!names(coffs) == "levels"] for(i in dataNames) { thisData<-coffs[[i]] last_plot() + geom_line(aes(y = thisData, colour = i)) } last_plot() + ylab("Total Chargeoffs") } coffs is a data.frame.

Hello, Is it possible somehow to get mouse coordinates without using the event mechanism ?

Hi. Is there any straightforward way to tell pointer position (x, y) upon keypress? In original wxWidgets, wxKeyEvent supports GetX() and GetY() methods, but wxRuby''s KeyEvent object does not have one. I also checked with event.methods and event.instance_variables. Do I need to keep track of pointer position by evt_motion? -- Taisuke Yamada <tyamadajp@spam.rakugaki.org>,

Hi: I would like to find out the panel of a xyplot matrix where a mouse clicked. I know this functionality is already bundled in trellis.focus but I can't use it because I am coding a stand alone application in Java using with GDCanvas as a graphics device. I tried calling trellis.focus from Java with: re.eval("t = trellis.focus()")); However it did not work for an embedded

If one wants to unload compiled code for a package containing a namespace, my understanding is that .onUnload() should be used, with a call to library.dynam.unload(). This is used in e.g., the stats and methods packages, but it appears to me that the compiled code is not being unloaded when the package is detached(). Am I misunderstanding something?

Hello, I have a package with a namespace. Because I use Roxygen that overwrites the NAMESPACE file each time it is run, I use a R/zzz.R file with an .onLoad() and .onUnload() functions to take care of loading and unloading my shared library. The problem: if I load my library from a local directory, then the unloading of the package fails, e.g: # loads fine >library(Foo,

Hi, I noticed that www.meebo.com has the ability that when you close the browser during a session, it prompts you , are you sure you want to close? How does it do this? I would like to use such an ability , so that if the user preempts a close on the browser, I can kill all threads I have running for that user. Thanks -- Posted via http://www.ruby-forum.com/.

Hi. I am having difficulty following section 1.6.6 of the R-extensions manual. I am trying to update the Brobdingnag package to include a NAMESPACE file (the untb package requires the Brobdingnag package). Without the NAMESPACE file, the package passes R CMD check cleanly. However, if I include a NAMESPACE file, even an empty one, R CMD check gives the following error in 00install.out:

I've noticed that many of the "base" R packages have an .onUnload() function which automatically unloads compiled shared libraries with library.dynam.unload(). For example: > stats:::.onUnload function (libpath) library.dynam.unload("stats", libpath) <bytecode: 0x1033b9c30> <environment: namespace:stats> I've noticed that many other packages don't

I have a package that I'm developing that I need to unload the library. Long story short I figured out that the leaving the compiled code loaded lead to a segmentation fault, but unloading the code will fix it. I've read the documentation and it appears that there are several ways to do this? What is the popper accepted current standard for unloading compiled code? The options as I
