similar to: Fw: Re: Linked List in R

Hi, I am trying to create a linked list in R by defining a class Node which has a instance variable Node. setClass("Node", representation(rate="numeric", nextNode="ANY")) The above works. But the following gives me a warning message. setClass("Node", representation(rate="numeric", nextNode="Node")) > >

Hi, I started this post on bioc-devel but this seems to be more general: https://stat.ethz.ch/pipermail/bioc-devel/2013-May/004311.html See reproducible example from Martin below. Thank you.

PkgA wishes to write a method for 'unique' on S4 class 'A'. ?Methods indicates that one should setGeneric("unique") setClass("A") unique.A <- function(x, incomparables=FALSE, ...) {} setMethod(unique, "A", unique.A) Both S3 and S4 methods need to be exported in the NAMESPACE import(methods) S3method(unique, A)

PkgA has a single R/binding.R file containing .A <- setRefClass("A", methods=list(initialize=function(...) {})) .onLoad <- function(...) .A() A NAMESPACE with import(methods) exportClasses("A") and DESCRIPTION Package: PkgA Type: Package Title: Documenting reference classes Version: 0.0.1 Date: 2012-08-05 Author: Martin

Hi Gabor, I just used your R code below and the code worked properly without any error messages. Attached is the output graph, which may be the one you expected. library("Rgraphviz") set.seed(123) V <- letters[1:10] M <- 1:4 g1 <- randomGraph(V, M, 0.2) g1 plot(g1) Thanks.

Hi Martin, It is really a 'PATH' problem. After adding C:\Program Files\Graphviz2.20\bin to the 'PATH' environment variable, the Rgraphviz package can be loaded without any error messages. Sorry that I ONLY set my 'PATH' environment variable correctly for R but not for Graphviz. Thank you and Duncan so much for your great help. Howard On Tue Mar 30 18:12:54

Loading an S4 object from a file without first loading the library sometimes (?, the example below and actual example involves a virtual base class and the show generic) leads to incorrect dispatch (to the base class method). The attached package reproduces the problem. It has setClass("A") setClass("B", contains="A") setMethod("show", "A",

Dear all, I have been trying to create an R package. This has been successfull until I tried to define classes. Currently, my procedure is the following: Start R, load the function and class definition >tmp <- function (x) {x} >setClass("rpa", contains = "list", where=topenv(parent.frame())) Use package skeleton to create directory structure:

In fact, this does reproduce on R-devel: > options(download.file.method = "libcurl") > options(repos = c(CRAN = "https://cran.rstudio.com/", CRANextra = + "http://www.stats.ox.ac.uk/pub/RWin")) > install.packages("lattice") ## could be any package Installing package into ?/Users/kevinushey/Library/R/3.3/library?

Hey everyone, I would like to develop a package using S4 classes. I have to define several S4 classes that inherits from each others as follow: # A <- B <- C <- D I also would like to define .DollarNames methods for these class so, if I have understood well, I also have to define an old class as follow: # AOld <- A <- B <- C <- D setOldClass(Classes = "AOld")

It would be convenient if, under R-devel r56422, packages that require re-installation because they do not have a NAMESPACE were marked as old.packages, so their lack of functionality can be discovered more easily. > "snow" %in% row.names(old.packages()) [1] FALSE > library(snow) Error in library(snow) : package 'snow' does not have a NAMESPACE and should be

Thanks, Martin. Based on my previous post, I thought of a more general formulation of my question that I think would be helpful to ask here. What's the best way to build an R object that links multiple datapoints about different people? I mean, I happen to have datasets that have individual gene expression data tied to individual patient characteristics (how long they survived, age, gender,
